== RCU Preempt support ==

Recommended LWN article: [http://lwn.net/Articles/253651/ "The design of preemptible read-copy-update"]

[http://en.wikipedia.org/wiki/Read-copy-update RCU] is a very powerful locking scheme used in Linux to scale to [http://lkml.org/lkml/2007/5/4/314 very large] number of CPUs on a single system. However, it wasn't well suited for the Real Time patchsets that have been developed to make Linux a RT OS, because some parts weren't preemptible, causing latencies too big for RT workloads. In 2.6.25, RCU can be preempted, eliminating that source of latencies and making Linux a bit more RT-ish.

== Better process memory usage measurement ==
Recommended LWN article: [http://lwn.net/Articles/230975/ "How much memory are applications really using?"]

Measuring how much memory processes are using is more dificult that it looks, specially when processes are sharing the memory used. Features like /proc/$PID/smaps (added in [http://kernelnewbies.org/Linux_2_6_14 2.6.14]) help, but it has not been enought. 2.6.25 adds new stadistics to make this task easier. A new /proc/$PID/pagemaps file is added for each process. In this file the kernel exports (in binary format) the physical page localization for each page used by the process. Comparing this file with the files of other processes allows to know what pages they are sharing. Another file, /proc/kpagemaps exposes another kind of statistics about the pages of the system. The author of the patch, Matt Mackall, proposes two new statistic metrics: "proportional set size" (PSS) - divide each shared page by the number of processes sharing it; and "unique set size" (USS) (counting of pages not shared). The first statistic, PSS, has also been added to each file in /proc/$PID/smaps. In [http://selenic.com/repo/pagemap/ this HG repository] you can find some sample command line and graphic tools that exploits all those statistics.

== EXT4 update ==
Recommended article: [http://lwn.net/Articles/266274/ "A better ext4"]

EXT4 mainline snapshot gets an update with a bunch of features: Multi-block allocation, large blocksize up to PAGEZIZE, journal checksumming, large file and filesystem support, inode versioning and allow in-inode extended attributes on the root inode. These features should be the last ones that require on-disk format changes. Other features that don't affect the disk format, like delayed allocation, have still to be merged.

== FIFO ticket spinlocks ==
Recommended article: [http://lwn.net/Articles/267968/ "Ticket spinlocks"]

In certain workloads, spinlocks can be unfair, ie: a process spinning on a spinlock can be starved up to 1.000.000 times. Usually starvation in spinlocks is not a problem, because it becomes a performance problem before any starvation is noticed, but testing has showed the contrary. And it's always possible to find a obscure corner case that will generate a lot of contention on some lock, and the processor that will grab the lock does it randomly. With the new spinlocks, the processes grab the spinlock in FIFO order. Spinlocks configured to run in more than 255 CPUs will also use a 32-bit value (instead of the 16 bits used when NR_CPUS < 255) that allows up to 65536 processors.
