Comprehensible changelog of the linux kernel. This page shows a summary of the important changes being added in each linux kernel release - support for new devices, new features (filesystems, subsystems), important internal changes, etc. While this text is aimed to be (unlike the full changelog) comprehensible, it's obvious that some parts will not be comprehensible for those who don't know a lot about kernel internals, just like it happens in every software project. Other places to get news about the linux kernel are [http://lwn.net/Kernel/ LWN kernel status], [http://lwn.net/Articles/driver-porting/ LWN driver porting guide], [http://lwn.net/Articles/2.6-kernel-api/ LWN list of API changes in 2.6], or [http://www.lkml.org www.lkml.org]. Before adding things here look at the [#rules RULES] section at the end of the page!

• Kernel Core changes

  • New features/frameworks

    • *at syscalls: introduce in total 13 new system calls which take a file descriptor/filename pair instead of a single file name. These functions (sys_openat, sys_mkdirat, sys_mknodat, sys_fchownat, sys_futimesat, sys_newfstatat, sys_unlinkat, sys_renameat, sys_linkat, sys_symlinkat, sys_readlinkat, sys_fchmodat, sys_faccessat) are needed to implement race-free filesystem traversal, they are necessary to implement a virtual per-thread current working directory (multi-threaded backup software, etc). Glibc today implements those interfaces using the /proc/self/fd magic, but this hack is rather expensive, and other operative systems like OpenSolaris [http://docs.sun.com/app/docs/doc/816-0212/6m6nd4nc7?a=view already have some of them]. In the GNU world, coreutils are already using them, and will have lots of other users too - every program which is walking the filesystem tree will benefit [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5590ff0d5528b60153c0b4e7b771472b5a95e297 (commit)].

    • Add pselect/ppoll system call implementation [http://lwn.net/Articles/176911/ (LWN article)] [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9f72949f679df06021c9e43886c9191494fdb007 (commit)].

    • Add unshare() system call. The linux kernel implements threads in a very simple and lightweight, handling them just as normal processes which happen to share resource with other threads (just like Windows and Solaris in recent Solaris versions). The clone() system call already allows to create new processes which can share different attributes (file descriptors, filesystem information, filesystem namespace, signal handlers, address space...). The unshare() system call adds a primitive to the Linux thread model that allows threads to selectively 'unshare' any resources that were being shared at the time of their creation. unshare() was [http://marc.theaimsgroup.com/?l=linux-kernel&m=96753366711611&w=2 conceptualized by Alexander Viro] in August of 2000. unshare() augments the usefulness of Linux threads for applications that would like to control shared resources without creating a new process. unshare() is a natural addition to the set of available primitives on Linux that implement the concept of process/thread as a virtual machine. For more info check the [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/unshare.txt Documentation]. [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=cf2e340f4249b781b3d2beb41e891d08581f0e10 (commit)], implementation for unsharing file descriptors [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a016f3389c06606dd80e687942ff3c71d41823c4 (commit)], vm structure (disabled in this release by default) [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a0a7ec308f1be5957b20a1a535d21f683dfd83f0 (commit)], filesystem namespace [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=741a295130606143edbf9fc740f633dbc1e6225f (commit)], filesystem info [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=99d1419d96d7df9cfa56bc977810be831bd5ef64 (commit)]. [http://lwn.net/Articles/135321/ (LWN article)]

    • New 'mutex' locking primitive. Until now, there was two main types of locks: spinlocks and semaphores. Mutexes are like a spinlock, but you may block holding a mutex. If you can't lock a mutex, your task will suspend itself, and be woken up when the mutex is released. This means the CPU can do something else while you are waiting. There are many cases when you simply can't sleep and so have to use a spinlock instead. Semaphores can be and have been (ab)used for this same purpose, but mutexes are simpler than semaphores, and have some advantages. You cannot use mutexes the same way you can use semaphores though, e.g. they cannot be used from an interrupt context, nor can they be unlocked from a different context that which acquired it. Read the [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/mutex-design.txt documentation], or (more interesting) [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=kernel/mutex.c kernel/mutex.c]; it also features some extensive debugging facilities in [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=kernel/mutex-debug.c kernel/mutex-debug.c] [http://lwn.net/Articles/165039/ (LWN article)] [http://lwn.net/Articles/167034/ (LWN article explaining the API)] [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=6053ee3b32e3437e8c1e72687850f436e779bd49 (commit)]

    • High resolution timers ([http://lwn.net/Articles/167897 LWN article explaining the API)]. In contrast to the low-resolution timeout API implemented in kernel/timer.c, hrtimers provide finer resolution and accuracy depending on system configuration and capabilities. These timers are currently used for: itimers, POSIX timers, nanosleep and precise in-kernel timing. For more details read the [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/hrtimers.txt documentation] [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=c0a3132963db68f1fbbd0e316b73de100fee3f08 (commit)]

    • Swap migration. [http://lwn.net/Articles/157066/ (LWN article)] Swap migration allows the moving of the physical location of pages between nodes in a NUMA system while the process is running, through swap. This means that the virtual addresses that the process sees do not change. However, the system rearranges the physical location of those pages. The main intent of page migration patches here is to reduce the latency of memory access by moving pages near to the processor where the process accessing that memory is running. The patchset allows a process to manually relocate the node on which its pages are located. The pages of process can also be relocated from another process using the sys_migrate_pages() function call. Swap migration works by simply evicting the page, the pages must be faulted back in. The pages are then typically reallocated by the system near the node where the process is executing. Manual migration is very useful if for example the scheduler has relocated a process to a processor on a distant node. A batch scheduler or an administrator can detect the situation and move the pages of the process nearer to the new processor. For more details, see the commit [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=45b07ef31d1182d2cfde7711327e3afb268bb1ac (commit)]. Also, add "direct migration" support on top of the swap based page migration facility: This allows the direct migration of anonymous pages and the migration of file backed pages by dropping the associated buffers (requires writeout) and fall back to swap if necessary [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a48d07afdf18212de22b959715b16793c5a6e57a (commit)]

    • Add /proc/sys/vm/drop_caches. Writing to this will cause the kernel to drop clean caches, dentries and inodes from memory, causing that memory to become free. This is mainly useful for benchmarking, for getting consistent results between filesystem benchmarks without rebooting. To free pagecache: "echo 1 > /proc/sys/vm/drop_caches", to free dentries and inodes: "echo 2 > /proc/sys/vm/drop_caches", to free pagecache, dentries and inodes: "echo 3 > /proc/sys/vm/drop_caches". As this is a non-destructive operation and dirty objects are not freeable, the user should run `sync' first [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9d0243bca345d5ce25d3f4b74b7facb3a6df1232 (commit)]

    • Implement madvise(MADV_REMOVE): This feature frees up a given range of pages and its associated backing store. Current implementation supports only shmfs/tmpfs and other filesystems return -ENOSYS. Databases want to use this feature to drop a section of their bufferpool (shared memory segments) - without writing back to disk/swap space. This feature is also useful for supporting hot-plug memory on UML [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=f6b3ec238d12c8cc6cc71490c6e3127988460349 (commit)]

    • Per-mountpoint noatime/nodiratime: turns noatime and nodiratime into per-mount instead of per-sb flags [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=fc33a7bb9c6dd8f6e4a014976200f8fdabb3a45c (commit)]

    • EDAC support. The EDAC goal is to detect and report errors that occur within the computer system. In the initial release, memory Correctable Errors (CE) and Uncorrectable Errors (UE) are the primary errors being harvested. Detecting CE events, then harvesting those events and reporting them, can be a predictor of future UE events. With CE events, the system can continue to operate, but with less safety. Preventive maintainence and proactive part replacement of memory DIMMs exhibiting CEs can reduce the likelihood of the dreaded UE events and system 'panics'. In addition, PCI Bus Parity and SERR Errors are scanned for on PCI devices in order to determine if errors are occurring on data transfers [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=da9bb1d27b21cb24cbb6a2efb5d3c464d357a01e (commit)]. Add drivers for Intel i82860, i82875 [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0d88a10e566d46bffc214c974e5cf5abe38d8da8 (commit)], for AMD 76x and Intel E750x, E752x [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=806c35f5057a64d3061ee4e2b1023bf6f6d328e2 (commit)] and Radisys 82600 [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2f768af73fea4c70f9046388a7ff648ad11f028e (commit)]

    • Tweaks to the NUMA policies in the slab allocator [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=dc85da15d42b0efc792b0f5eab774dc5dbc1ceec (commit)]

    • Implement a generic dispatch queue for all the I/O schedulers [http://lwn.net/Articles/157208/ (LWN article)] [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8922e16cf6269e668123acb1ae1fdc62b7a3a4fc (commit)], [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b4878f245ec8e168cdd1f170f823a750b7dd4af5 (commit)]

  • Process scheduler

    • Add a 'domain distance' function, which is used to cache measurement results for machiens with several nodes. Each distance is only measured once. This means that e.g. on NUMA distances of 0, 1 and 2 might be measured, on HT distances 0 and 1, and on SMP distance 0 is measured. The code walks the domain tree to determine the distance, so it automatically follows whatever hierarchy an architecture sets up. This cuts down on the boot time significantly and removes the old O(N^2) limit. For more details, see the commit [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=198e2f181163233b379dc7ce8a6d7516b84042e7 (commit)]

    • Filter affine wakeups [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d7102e95b7b9c00277562c29aad421d2d521c5f6 (commit)]

    • Add a new SCHED_BATCH (3) scheduling policy: such tasks are presumed CPU-intensive, and will acquire a constant +5 priority level penalty. Such policy is nice for workloads that are non-interactive, but which do not want to give up their nice levels. The policy is also useful for workloads that want a deterministic scheduling policy without interactivity causing extra preemptions (between that workload's tasks) [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b0a9499c3dd50d333e2aedb7e894873c58da3785 (commit)]

  • Huge pages

    • Implement copy-on-write support for hugetlb mappings so MAP_PRIVATE can be supported. This helps us to safely use hugetlb pages in many more applications [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=1e8f889b10d8d2223105719e36ce45688fedbd59 (commit)]

    • Make hugepages obey cpusets [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=aea47ff363c15b0be5fc27ed991b1fdee338f0a7 (commit)]

    • Add NUMA policy support for huge pages: The huge_zonelist() function in the memory policy layer provides an list of zones ordered by NUMA distance. The hugetlb layer will walk that list looking for a zone that has available huge pages but is also in the nodeset of the current cpuset [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5da7ca86078964cbfe6c83efc1205904587706fe (commit)]

  • Performance / size optimizations

    • Shrink struct page in some configurations using anonymous struct [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=349aef0bc4c7f07d685c977e12d0e2d0b5d0e6db (commit)]

    • Shrink dentry struct: Some long time ago, dentry struct was carefully tuned so that on 32 bits UP, sizeof(struct dentry) was exactly 128, ie a power of 2, and a multiple of memory cache lines. Then RCU was added and dentry struct enlarged by two pointers, with nice results for SMP, but not so good on UP, because breaking the above tuning (128 + 8 = 136 bytes). This reverts this unwanted side effect using a union. As dentry cache easily contains millions of entries, a size reduction is worth the extra complexity of the ugly C union [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5160ee6fc891a9ca114be0e90fa6655647bb64b2 (commit)]

    • Add the SLOB allocator, a configurable replacement for slab allocator. This adds a CONFIG_SLAB option under CONFIG_EMBEDDED. SLOB is a traditional K&R/UNIX allocator with a SLAB emulation layer, similar to the original Linux kmalloc allocator that SLAB replaced. It's signicantly smaller code and is more memory efficient. But like all similar allocators, it scales poorly and suffers from fragmentation more than SLAB, so it's only appropriate for small systems who want to save some memory [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=10cef6029502915bdb3cf0821d425cf9dc30c817 (commit)]

    • Make vm86 support optional under CONFIG_EMBEDDED, to save about 5k of kernel size [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=64ca9004b819ab87648dbfc78f3ef49ee491343e (commit)]

    • Abandon GCC 2.9x support. It doesn't support useful features already used by some drivers like anonymous unions. Plus, no new distros are shipping with 2.9x compilers. In other words, supporting it has more disadvantages than advantages. The minium required compiler version us GCC 3.2 [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=fd285bb54d8a3e99810090ae88cfe8ed77d1da25 (commit)]

    • cpuset: Provide a simple per-cpuset metric of memory pressure, tracking the -rate- that the tasks in a cpuset call try_to_free_pages(), the synchronous (direct) memory reclaim code. This enables batch managers monitoring jobs running in dedicated cpusets to efficiently detect what level of memory pressure that job is causing. For more details, see the commit [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3e0d98b9f1eb757fc98efc84e74e54a08308aa73 (commit)]

    • Make high and batch sizes of per_cpu_pagelists configurable, as recently there has been lot of traffic on the right values for batch and high water marks for per_cpu_pagelists. A new tunable /proc/sys/vm/percpu_pagelist_fraction is added. This entry controls the fraction of pages at most in each zone that are allocated for each per cpu page list. The min value for this is 8. It means that we don't allow more than 1/8th of pages in each zone to be allocated in any single per_cpu_pagelist. The batch value of each per cpu pagelist is also updated as a result [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8ad4b1fb8205340dba16b63467bb23efc27264d6 (commit)]

    • swsusp: remove the image encryption that is only used by swsusp instead of zeroing the image after resume in order to prevent someone from reading some confidential data from it in the future and it does not protect the image from being read by an unauthorized person before resume.

    • swsusp: make suspend image size limit tunable via /sys/power/image_size. It is necessary for systems on which there is a limited amount of swap available for suspend.

  • PPC

    • SPU file system. The SPU file system is used on PowerPC machines that implement the Cell Broadband Engine Architecture (aka: Cell processors) in order to access Synergistic Processor Units (SPUs). The file system provides a name space similar to posix shared memory or message queues. Users that have write permissions on the file system can use spu_create(2) to establish SPU contexts in the spufs root. Every SPU context is represented by a directory containing a predefined set of files. These files can be used for manipulating the state of the logical SPU.

QDIO and Hiper Sockets processing in z/VM V=V guest environments (as well as V=R with z/VM running in LPAR mode) requires shadowing of all QDIO architecture queue elements.

• Filesystems

  • OCFS2: Clustering filesystem contributed by Oracle (Oracle-Cluster-File-System). It's general purpose extent based shared disk cluster filesystem with many similarities with ext3, support for 64 bit inode numbers, and has automatically extending metadata groups which may also make it attractive for non-clustered use. It includes a simple heartbeat implementation for monitoring which nodes come and go and a distributed lock manager called "dlm" [http://lwn.net/Articles/137278/ (LWN article)], [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=29552b1462799afbe02af035b243e97579d63350 (commit)]

  • Configfs: It's a ram-based filesystem that provides the converse of sysfs's functionality. Where sysfs is a filesystem-based view of kernel objects, configfs is a filesystem-based manager of kernel objects, or config_items. With sysfs, an object is created in kernel (for example, when a device is discovered) and it is registered with sysfs. Its attributes then appear in sysfs, allowing userspace to read the attributes via readdir(3)/read(2). It may allow some attributes to be modified via write(2). The important point is that the object is created and destroyed in kernel, the kernel controls the lifecycle of the sysfs representation, and sysfs is merely a window on all this. Both sysfs and configfs can and should exist together on the same system. One is not a replacement for the other [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7063fbf2261194f72ee75afca67b3b38b554b5fa (commit)]

  • FUSE: Make the maximum size of write data configurable by the filesystem. The previous fixed 4096 limit only worked on architectures where the page size is less or equal to this. This change make writing work on other architectures too, and also lets the filesystem receive bigger write requests in direct_io mode. Normal writes which go through the page cache are still limited to a page sized chunk per request [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3ec870d524c9150add120475c8ddcfa50574f98e (commit)]

  • NFS: support large reads and writes on the wire. Most NFS server implementations allow up to 64KB reads and writes on the wire. The Solaris NFS server allows up to a megabyte, for instance. Now the Linux NFS client supports transfer sizes up to 1MB, too. This will help reduce protocol and context switch overhead on read/write intensive NFS workloads, and support larger atomic read and write operations on servers that support them [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=40859d7ee64ed6bfad8a4e93f9bb5c1074afadff (commit)]

  • v9fs: add readpage support. v9fs mmap support was originally removed to make mergin easier, but there have been requests from folks who want readpage functionality (primarily to enable execution of files mounted via 9P).

  • Add IFB (Intermediate Functional Block) network device: a new device to do intermediate functional block in a system shared manner. The new functionality can be grouped as: 1) qdiscs/policies that are per device as opposed to system wide. ifb allows for a device which can be redirected to thus providing an impression of sharing. 2) Allows for queueing incoming traffic for shaping instead of dropping. Packets are redirected to this device using tc/action mirred redirect construct [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=253af4235d24ddfcd9f5403485e9273b33d8fa5e (commit)]

  • LSM-IPSec: Security association restriction: implement per packet access control via the extension of the Linux Security Modules (LSM) interface by hooks in the XFRM and pfkey subsystems that leverage IPSec security associations to label packets. Such access controls augment the existing ones based on network interface and IP address. The former are very coarse-grained, and the latter can be spoofed. By using IPSec, the system can control access to remote hosts based on cryptographic keys generated using the IPSec mechanism. This enables access control on a per-machine basis or per-application if the remote machine is running the same mechanism and trusted to enforce the access control policy.

  • Netfilter ip_tables: NUMA-aware allocation. Part of a performance problem with ip_tables is that memory allocation is not NUMA aware, but 'only' SMP aware (ie each CPU normally touch separate cache lines). Even with small iptables rules, the cost of this misplacement can be high on common workloads. Instead of using one vmalloc() area (located in the node of the iptables process), we now allocate an area for each possible CPU, using vmalloc_node() so that memory should be allocated in the CPU's node if possible [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=318360646941d6f3d4c6e4ee99107392728a4079 (commit)]

• STILL NOT RELEASED!

• Overview
  • sys_splice syscall

  • Lightweight robust futexes [http://lwn.net/Articles/172149/ (LWN article)]

  • Block queue IO tracing

  • New scheduler domain which optimizes scheduling decisions for multi-core CPUs sharing caches
  • Generic RTC subsystem

  • Raid5 reshaping support [http://lwn.net/Articles/169140/ (LWN article)]

  • iptables support for H.323 protocol, 64-to-32bit compatibility for 32-bit iptables userspace tools running in a 64-bit kernel
  • 64-to-32-bit socket ioctl compatibility
  • Add support for Router Preference (RFC4191), Router Reachability Probing (RFC4191) and experimental support for Route Information Option in RA (RFC4191) in IPV6
  • CCID2 support for DCCP

• Kernel Core changes

  • Core

    • Introduce the sys_splice() system call. A pipe is used as small kernel buffer that you can use to transfer data from one end to the other. The idea and first implementation were done by Linus Torvalds [http://marc.theaimsgroup.com/?l=linux-kernel&m=110507985702357&w=2 (mail)], [http://marc.theaimsgroup.com/?l=linux-kernel&m=110511497731192&w=2 (mail)], [http://marc.theaimsgroup.com/?l=linux-kernel&m=110511787707447&w=2 (mail)]. It's a "better sendfile()", it can take input from anything (not just file -> socket) that just has "splice_read()", and move it to anything else, without doing any extra copies of the data. For example, a digital video camera could stream to both a file and live video (or something else) without doubling the buffering and doing memcpy [http://lwn.net/Articles/178199/ (LWN article)] [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5274f052e7b3dbd81935772eb551dfd0325dfa9d (commit)]

    • Add a new scheduler domain for representing multi-core with shared caches between cores. Consider a dual package system, each package containing two cores and with last level cache shared between cores with in a package. If there are two runnable processes, with this appended patch those two processes will be scheduled on different packages. On such systems, with this patch we have observed 8% perf improvement with specJBB (2 warehouse) benchmark and 35% improvement with CFP2000 rate (with 2 users). This new domain will come into play only on multi-core systems with shared caches. On other systems, this sched domain will be removed by domain degeneration code. This new domain can be also used for implementing power savings policy (see OLS 2005 [http://www.linuxsymposium.org/2005/view_abstract.php?content_key=109 CMP kernel scheduler paper] for more details) [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=1e9f28fa1eb9773bf65bae08288c6a0a38eef4a7 (commit)]

    • Lightweight robust futexes. "Robustness" is about dealing with crashes while holding a lock: if a process exits prematurely while holding a pthread_mutex_t lock that is also shared with some other process (e.g. yum segfaults while holding a pthread_mutex_t, or yum is kill -9-ed), then waiters for that lock need to be notified that the last owner of the lock exited in some irregular way. To solve such types of problems, "robust mutex" userspace APIs were created: pthread_mutex_lock() returns an error value if the owner exits prematurely - and the new owner can decide whether the data protected by the lock can be recovered safely.

    • Introduce a user space interface for swsusp. The interface is based on a special character device, called the snapshot device, that allows user space processes to perform suspend and resume-related operations with the help of some ioctls and the read()/write() functions. Additionally it allows these processes to allocate free swap pages from a selected swap partition, called the resume partition, so that they know which sectors of the resume partition are available to them. The interface uses the same low-level system memory snapshot-handling functions that are used by the built-it swap-writing/reading code of swsusp.

    • APIs

      • Deprecate the use of MS_VERBOSE and replace it with MS_SILENT [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9b04c997b1120feefa1e6ee8e2902270bc055cd2 (commit)]

      • Add API for flushing Anon pages: Currently, get_user_pages() returns fully coherent pages to the kernel for anything other than anonymous pages. This is a problem for things like fuse and the SCSI generic ioctl SG_IO which can potentially wish to do DMA to anonymous pages passed in by users. The fix is to add a new memory management API: flush_anon_page() which is used in get_user_pages() to make anonymous pages coherent [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=03beb07664d768db97bf454ae5c9581cd4737bb4 (commit)]

      • Add flush_kernel_dcache_page() API: We have a problem in a lot of emulated storage in that it takes a page from get_user_pages() and does something like: kmap_atomic(page; modify page; kunmap_atomic(page). However, nothing has flushed the kernel cache view of the page before the kunmap. We need a lightweight API to do this, so this new API would specifically be for flushing the kernel cache view of a user page which the kernel has modified. The driver would need to add flush_kernel_dcache_page(page) before the final kunmap [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5a3a5a98b6422d05c39eaa32c8b3f83840c7b768 (commit)]

      • 2TB files: Add blkcnt_t as the type of inode.i_blocks. This enables you to make the size of blkcnt_t either 4 bytes or 8 bytes on 32 bits architecture with CONFIG_LSF. On h8300, i386, mips, powerpc, s390 and sh that define sector_t, blkcnt_t is defined as u64 if CONFIG_LSF is enabled; otherwise it is defined as unsigned long. On other architectures, it is defined as unsigned long [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a0f62ac6362c168754cccb36f196b3dfbddc3bc3 (commit)]

      • for_each_possible_cpu: defines for_each_possible_cpu, a for-loop over cpu_possible_map. for_each_online_cpu is for-loop cpu over cpu_online_map......for_each_cpu() is not sufficiently explicit and can lead to mistakes.

      • unify pfn_to_page: There are 3 memory models, FLATMEM, DISCONTIGMEM, SPARSEMEM. Each arch has its own page_to_pfn(), pfn_to_page() for each models. But most of them can use the same arithmetic. This patch adds asm-generic/memory_model.h, which includes generic page_to_pfn(), pfn_to_page() definitions for each memory model. When CONFIG_OUT_OF_LINE_PFN_TO_PAGE=y, out-of-line functions are used instead of macro. This is enabled by some archs and reduces text size [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a117e66ed45ac0569c039ea60bd7a9a61e031858 (commit)]

      • Notifier chain: Introduces three new, parallel APIs: one for blocking notifiers, one for atomic notifiers, and one for "raw" notifiers (which is really just the old API under a new name) [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e041c683412d5bf44dc2b109053e3b837b71742d (commit)]

      • add EXPORT_SYMBOL_GPL_FUTURE(): This patch adds the ability to mark symbols that will be changed in the future, so that kernel modules that don't include MODULE_LICENSE("GPL") and use the symbols, will be flagged and printed out to the system log [http://lwn.net/Articles/171838/ (LWN article)] [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9f28bb7e1d0188a993403ab39b774785892805e1 (commit)]

    • CFQ:

      • Seek and async performance tuning: Detect whether a given process is seeky and if so disable (mostly) the idle window if it is. We still allow just a little idle time, just enough to allow that process to submit a new request. That is needed to maintain fairness across priority groups. In some cases, we could setup several async queues. This is not optimal from a performance POV, since we want all async io in one queue to perform good sorting on it. It also impacted sync queues, as async io got too much slice time [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=206dc69b31ca05baac68c75b8ed2ba7dd857d273 (commit)]

      • Change cfq io context linking from list to tree: On setups with many disks, we spend a considerable amount of time looking up the process-disk mapping on each queue of io. Testing with a NULL based block driver, this costs 40-50% reduction in throughput for 1000 disks [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e2d74ac0664c89757bde8fb18c98cd7bf53da61c (commit)]

    • cpuset memory spread page cache implementation and hooks: Change the page cache allocation calls to support cpuset memory spreading. See the previous patch, cpuset_mem_spread, for an explanation of cpuset memory spreading. On systems without cpusets configured in the kernel, this is no change. On systems with cpusets configured in the kernel, but the "memory_spread" cpuset option not enabled for the current tasks cpuset, this adds a call to a cpuset routine and failed bit test of the processor state flag PF_SPREAD_PAGE. On tasks in cpusets with "memory_spread" enabled, this adds a call to a cpuset routine that computes which of the tasks mems_allowed nodes should be preferred for this allocation. If memory spreading applies to a particular allocation, then any other NUMA mempolicy does not apply [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=44110fe385af23ca5eee8a6ad4ff55d50339097a (commit)]

    • cpuset memory spread basic implementation: This patch provides the implementation and cpuset interface for an alternative memory allocation policy that can be applied to certain kinds of memory allocations, such as the page cache (file system buffers) and some slab caches (such as inode caches). The policy is called "memory spreading." If enabled, it spreads out these kinds of memory allocations over all the nodes allowed to a task, instead of preferring to place them on the node where the task is executing. All other kinds of allocations, including anonymous pages for a tasks stack and data regions, are not affected by this policy choice, and continue to be allocated preferring the node local to execution, as modified by the NUMA mempolicy. There are two boolean flag files per cpuset that control where the kernel allocates pages for the file system buffers and related in kernel data structures. They are called 'memory_spread_page' and 'memory_spread_slab'. If the per-cpuset boolean flag file 'memory_spread_page' is set, then the kernel will spread the file system buffers (page cache) evenly over all the nodes that the faulting task is allowed to use, instead of preferring to put those pages on the node where the task is running. If the per-cpuset boolean flag file 'memory_spread_slab' is set, then the kernel will spread some file system related slab caches, such as for inodes and dentries evenly over all the nodes that the faulting task is allowed to use, instead of preferring to put those pages on the node where the task is running. This policy can provide substantial improvements for jobs that need to place thread local data on the corresponding node, but that need to access large file system data sets that need to be spread across the several nodes in the jobs cpuset in order to fit. Without this patch, especially for jobs that might have one thread reading in the data set, the memory allocation across the nodes in the jobs cpuset can become very uneven [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=825a46af5ac171f9f41f794a0a00165588ba1589 (commit)]

    • cpuset memory spread: slab cache format: Rewrap the overly long source code lines resulting from the previous patch's addition of the slab cache flag SLAB_MEM_SPREAD.

    • cpuset memory spread: slab cache filesystems: Mark file system inode and similar slab caches subject to SLAB_MEM_SPREAD memory spreading. If a slab cache is marked SLAB_MEM_SPREAD, then anytime that a task that's in a cpuset with the 'memory_spread_slab' option enabled goes to allocate from such a slab cache, the allocations are spread evenly over all the memory nodes (task->mems_allowed) allowed to that task, instead of favoring allocation on the node local to the current cpu [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=4b6a9316fab51af611dc8671f296734089f6a22a (commit)]

    • cpuset memory spread slab cache implementation: Provide the slab cache infrastructure to support cpuset memory spreading See the previous patches, cpuset_mem_spread, for an explanation of cpuset memory spreading. This patch provides a slab cache SLAB_MEM_SPREAD flag. If set in the kmem_cache_create() call defining a slab cache, then any task marked with the process state flag PF_MEMSPREAD will spread memory page allocations for that cache over all the allowed nodes, instead of preferring the local (faulting) node. On systems not configured with CONFIG_NUMA, this results in no change to the page allocation code path for slab caches. On systems with cpusets configured in the kernel, but the "memory_spread" cpuset option not enabled for the current tasks cpuset, this adds a call to a cpuset routine and failed bit test of the processor state flag PF_SPREAD_SLAB. This patch provides the generic slab flags and logic needed to apply memory spreading to a particular slab.

    • Use -mtune=generic for generic kernels. The upcomming gcc 4.2 got a new option -mtune=generic to tune code for both common AMD and Intel CPUs. Use this option when available for generic kernels. On x86-64 it is used with CONFIG_GENERIC_CPU. On i386 it is enabled with CONFIG_X86_GENERIC. It won't affect the base line CPU support in any ways and also not the minimum supported CPU [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=dca99a38bccceda9e079d4c95abefbd9028605fe (commit)]

    • SMP "alternatives" for x86-32. This features detects the configuration of the system at boot time, and patches certain instructions in the kernel image on the fly with optimized versions for UP or SMP, depending on what system is running. This is useful for distros, who can provide a single kernel which auto-optimizes itself for UP or SMP environments. The feature can patch both SMP->UP and UP->SMP.

If there are pci devices that need to be inserted/removed after the dock event, the event notification will be handed down to the normal pci hotplug event handler in acpiphp so that new bridges/devices can be enumerated. Because some dock stations do not have pci bridges or pci devices that need to be inserted after a dock, acpiphp will remain loaded to handle dock events even if no hotpluggable pci slots are discovered.

• If there's a interesting email (benchmarks, announcements if there's no web page, etc) about it in the mailing lists, get a link in one of the list's archives (at http://marc.theaimsgroup.com/?l=linux-kernel please, just for coherence. There're also fsdev & netdev mailing lists, etc) and add it.

• Add commit's link to the git's web interface if possible, using the "(commit)" word.

• To find commit's links you can search in the [http://www.kernel.org/git git web interface]. Remember that there're two main GIT trees where you can search for commits: [http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git the one which has all the stuff committed after 2.6.12-rc2] (ie: current development) and [http://kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git the one which has all the stuff BEFORE 2.6.12-rc2]

• However, if you want to keep track in "realtime", do NOT use the git's web interface (or the RSS). The RSS gets overflowed when there's a big merge. And more importantly, the shortlog you find in git's web interface does NOT care when things were really "committed": If a developer writes a patch, merges it in his git repository and then Linus pulls and merges it a month after it was merged in the developer's repository , the commit data won't appear in the "todays shortlog", but in the one-month-old changes (this could be fixed in the future however).

• IOW: To keep track of the linux merges in realtime, the best option is to [http://vger.kernel.org/vger-lists.html#git-commits-head subscribe to the git-commits-head] mailing list (or search in the archives). Commit IDs are in the X-Git-Commit mail header. Tell your mailer to show them (by default it will be hidden unless you activate the "see the whole mail" option), if your mailer is good enought you'll be able to add a script which gets the Commit ID out of the header and launch a browser with the "http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=" needed gitweb URL before it.

• It may look too hard to review the thousands of emails you get from the git-commit-head list, get the commit ID, the URL, a description and format all of it to put it here: "Formatting" is what would take most of your time. But the fact is that you can avoid most of the hard job by using some tricks. First of all, most of the relevant commits will be merged (and sent to the git-commits-head list) in the first two weeks after a kernel is released. When the mailing list sends you the commit messages, use the "mark" feature of your mailer to mark important commits - this is a easy operation, since the subject tells you if the commit is important, you can review quite a lot of commit messages per minute. When you're done, create an action/filter/whatever which allows you to extract the commit id. My MUA (sylpheed) allows me to create an "action" which allows me to pass the selected message(s) to a command. This allows to me to order my messages by marked/umarked to make easier to select at the same time all the marked messages, the I tell sylpheed to execute the previous "action", which runs a scripts which "greps" the commit-id out of the email headers and appends it to a file. This way I get a file with a list of all the relevant commit IDs (Other MUAS could have another methods to achieve this same goal or not have any at all). Now, with a local linux git repository (updated to head) and with a bit of scripting you can get (with git) the changelog information of every commit ID, so you can parse that information and generate a wiki-compatible-syntax list of commits with descriptions, URLs to gitweb automatically generated, etc. You'll need to fix the descriptions, but you get a LOT of work done automatically.
• The web interface will show "meta-commits". When Linus merges things from a remote repository, You'll see a "Merge git://git.domain.com/foo/bar" style of message commit. If you click it for details you'll see a huge merge, but then the git shortlog will also show the individual commits. So those "meta-commits" are useful to add links to big merges which do one thing but do not mean anything by themselves. Those "meta-commits" will not be mailed to the git-commits-head mailing list.
