1. Prominent features

1.1. NT synchronization primitive driver for faster games

The Windows NT operating systems offer some synchronization primitives that are too different to the ones present on Unix system. This creates performance problems when trying to emulate this behavior for software like Wine. This release adds a driver that allows to model NT's primitives and spend less time trying to emulate it, which can improve performance massively in some cases (particularly, games)

Documentation: NT synchronization primitive driver

Recommended LWN article: Windows NT synchronization primitives for Linux

1.2. Btrfs RAID1 read balancing

Btrfs uses a PID-based approach to distribute reads to the devices that are part of a RAID1 setup: this is optimal for many configurations, but not all. This release adds three new RAID1 read balancing methods that help to distribute reads I/O across devices: rotation (keeps all devices active - for now, it's preferable as the default), latency (smarter with failing/unstable block layer transport), and devid (manual control). They are enabled under the CONFIG_BTRFS_DEBUG config option and are on top of the previously added /sys/fs/btrfs/<UUID>/read_policy interface to configure the desired RAID1 read balancing method.

1.3. Support for uncached buffered I/O

This release adds support for optionally sending buffered I/O whose pages will be dropped from the page cache once the data is read/written. The reason for this feature are fast storage devices that can fill the RAM with too much page cache that will not be needed, with this feature it is possible to read/write data and drop it from the cache without facing the disadvantages and complexity of dealing with Direct I/O.

1.4. fsnotify file pre-access notification event

This release adds a new fsnotify event (FS_PRE_ACCESS) that gets generated before a file contents is accessed. The event is synchronous so if there is listener for this event, the kernel waits for reply. On success the execution continues as usual, on failure we propagate the error to userspace. This even allows userspace to fill in file content on demand from slow storage.

1.5. dmem cgroup for better control of GPU memory resources

It is desirable to prevent GPU workloads from being terminated. This release uses cgroups to prevent eviction. Both GPU and driver-allocated CPU memory will be accounted to the correct cgroup, and eviction would be made cgroup aware. This allows the GPU to be partitioned into cgroups, that will allow jobs to run next to each other without interference.

Documentation: DMEM

1.6. FUSE support for io_uring-based communication

This release adds FUSE support for io-uring communication between kernel and userspace, with the purpose of increasing FUSE performance (reducing context switches, etc)

Documentation: FUSE-over-io-uring design documentation

Recommended LWN article: FUSE and io_uring

1.7. Add amdxdna driver for AMD NPUs

This driver adds support for AMD NPUs (Neural Processing Unit), an AI inference accelerator integrated into AMD client CPUs. It enables efficient execution of Machine Learning applications like CNNs, LLMs, etc. It is based on AMD XDNA architecture.

Documentation: AMD XDNA™ Architecture

1.8. XFS reflink and reverse-mapping support for the realtime device

The XFS realtime device has added support for reflink and reverse-mapping.

1.9. NFSv4.2+ attribute delegation

This release implements NFSv4.2+ attribute delegation. An attribute delegation permits an NFS client to manage a file's mtime, rather than flushing dirty data to the NFS server so that the file's mtime reflects the last write, which is considerably slower.

IETF draft: Extending the Opening of Files in NFSv4.2

1.10. x86 TLB flushing scalability optimizations

This release includes some TLB flushing scalability optimizations to update some data structures lazily during context switches. This improves performance in some microbenchmarks

2. Core (various)

(FEATURED) Introduce a new fsnotify event (FS_PRE_ACCESS) that gets generated before a file contents is accessed. The event is synchronous so if there is listener for this event, the kernel waits for reply. On success the execution continues as usual, on failure we propagate the error to userspace.

 * Overview (useful for headlines):
   * OCFS2 (http://lwn.net/Articles/137278/, http://oss.oracle.com/projects/ocfs2/), a clustering filesystem contributed by Oracle, first clustering filesystem available in linux mainline tree (there's GFS http://www.redhat.com/software/rha/gfs, shipped out-of-the-tree by Red Hat)
   * new unshare() ( http://lwn.net/Articles/135321/), pselect()/ppoll() and *at() system calls (http://lwn.net/Articles/164887/)
   * support the moving of the physical location of pages between nodes in NUMA systems
   * support for the Cell processor
   * cpufreq support for G5s plus thermal control for dualcore G5s
   * improved power management support for many devices and subsystems (libata, alsa...)
   * mutex locking primitive
   * high-resolution timers (http://lwn.net/Articles/167897)
   * per-mountpoint noatime/nodiratime
   * 64-to-32-bit ioctl compatibilty for the v4l2 subsystem
   * IPv6 support for DCCP, a new TIPC (Transparent Inter Process Communication, http://tipc.sourceforge.net/) protocol for intra-clustering communication
   * ACL support for CIFS filesystem
   * HFSX filesystem support
   * new configfs filesystem (which complements sysfs, not replaces it)
   * support for running executables from v9fs (plan9 9P distributed filesystem)
   * support for many new devices, improved support and features for others and lots of other changes.

 * '''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://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 [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://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)]




  * 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)]
   * configurable support for ELF core dumps, saves about 5K [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=708e9a794cf8822b760edaccd9053edb07c34d19 (commit)]
   * Make x86 doublefault handling optional, saves about 13 KB [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=22c4e3084eb8b88288a622a57d8b35c450a439f2 (commit)]
   * Make *[ug]id16 support optional, saves around 2 Kb [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e585e47031751f4e393e10ffd922885508b958dd (commit)]
   * Add scripts/bloat-o-meter script (python) to measure size changes in the functions of a given file [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d960600df3ce3588571e2c1adf1f5f6d8ca9eb5a (commit)]

  * Various changes
   * TTY layer buffering revamp, see the commit link [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=33f0f88f1c51ae5c2d593d26960c760ea154c2e2 (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.

  * 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.

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)]
  * NFSv4: Allow user to set the port used by the NFSv4 callback channel with the nfs.callback_tcpport boot option [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a72b44222d222749d54b3e370d825094352e389f (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). This patch adds readpage support (but not writepage which contained most of the objectionable code) [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=147b31cf09ee493aa71c87c0dd2eef74b6b2aeba (commit)]. Add new and more efficient multiplexer implementation [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3cf6429a26da5c4d7b795e6d0f8f56ed2e4fdfc0 (commit)] and zero copy implementation to reduce the number of copies in the data and stat paths [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=531b1094b74365dcc55fa464d28a9a2497ae825d (commit)]
  * ext3: external journal device as a mount option. The syntax is : "# mount -t ext3 -o journal_dev=0x0820 ...", where 0x0820 means major=8 and minor=32 [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=71b9625744b7d4a6a2416389a5ba464bdf11f07f (commit)]

  * RelayFS: Add support for global relay buffers. This can be used by clients to create a single global relayfs buffer instead of the default per-cpu buffers. This was suggested as being useful for certain debugging applications where it's more convenient to be able to get all the data from a single channel without having to go to the bother of dealing with per-cpu files [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e6c08367b8fc6dce6dfd1106f53f6ef28215b313 (commit)].

 * '''Networking'''
  * TIPC (Transparent Inter Process Communication). TIPC is a protocol designed for intra cluster communication.

  * Netfilter x_tables, an abstraction layer for {ip,ip6,arp}_tables: This tries to do the best job for unifying the data structures and backend interfaces for the three evil clones ip_tables, ip6_tables and arp_tables [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2e4e6a17af35be359cc8f1c924f8f198fbd478cc (commit)]
  * 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. [http://www.selinux-symposium.org/2005/presentations/session2/2-3-jaeger.pdf paper], [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5e0f76c6bbc0d26cd9625876f7beeb7b002f39bf (commit)]
  * TCP BIC: CUBIC window growth (2.0). Replace existing BIC version 1.1 with new version 2.0. The main change is to replace the window growth function with a cubic function as described in http://www.csc.ncsu.edu/faculty/rhee/export/bitcp/cubic-paper.pdf [http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=df3271f3361b61ce02da0026b4a53e63bc2720cb (commit)]
  * 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)]

Rules:

 * Name of the new feature/description of the change, including a small explanation if possible
 * If its a feature and the feature has some web page add a link to it
 * If there's a paper (OLS!) or an article add a link to it. Or write one ;-)
 * If there's a interesting mail (benchmarks, announcements if there's no web page, etc) about it in the mailing list, get a link in one of the list's archives (at http://marc.theaimsgroup.com/?l=linux-kernel please, just for coherence) and add the link here
 * Add commit's link if possible. For commits add a "(commit)" word and add the link there. Don't add the commit link to another word (please).
 * Keeping realtime track of the commits is really, really easy. Just [http://vger.kernel.org/vger-lists.html#git-commits-head subscribe to the git-commits-head] mailing list (or look at the archives). Commit IDs are in the X-Git-Commit mail header (tell your mailer to show them, 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=" URL before it.
 * Do NOT use the [http://www.kernel.org/git git web interface] (or RSS) to keep track of the commits. The RSS gets overflowed when Linus does a big merge, and more importantly, the shortlog doesn't care about when things were committed. If a developer writes a patch, merges it in his git repository and then Linus merges it in mainline after a month, the commit won't appear in the "todays shortlog", but in the one which contains the one-month-old changes.
 * Git has "meta-commits", though. When Linus merges things from a remote repository, You'll see a "Merge git://git.domain.com/foo/bar" style of message commit. The one-month-old commit won't appear in the shortlog but the remote repository merge will, and if you check the details of the remote-repository-merge commit ID it'll look like a huge patch. It's a "meta-commit" though, and the individual commits will appear in the shortlog too.
 * Still, the web interface has a useful search field.
 * 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] 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]
