LINUX 
Kernels
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) readable, 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 LWN kernel status, LWN driver porting guide, LWN list of API changes in 2.6, or www.lkml.org. If you're going to add something here look first at LinuxChangesRules!

Introduce the splice(), tee() and vmsplice() system calls, a new I/O method. (LWN article about splice()), (LWN article about tee()), (LWN article about vmsplice()) The idea behind splice is the availability of a in-kernel buffer that the user has control over, where "splice()" moves data to/from the buffer from/to an arbitrary file descriptor, while "tee()" copies the data in one buffer to another, ie: it "duplicates" it. The in-buffer however is implemented as a set of reference-counted pointers which the kernel copies around without actually copying the data. So while tee() "duplicates" the in-kernel buffer, in practice it doesn't copy the data but increments the reference pointers, avoiding extra copies of the data. In the same way, splice() can move data from one end to another, but instead of bringing the data from the source to the process' memory and sending back to the destination it just moves it avoiding the extra copy. This new scheme can be used anywhere where a process needs to send something from one end to another, but it doesn't need to touch or even look at the data, just forward it: Avoiding extra copies of data means you don't waste time copying data around (huge performance improvement). For example, you could forward data that comes from a MPEG-4 hardware encoder, and tee() it to duplicate the stream, and write one of the streams to disk, and the other one to a socket for a real-time network broadcast. Again, all without actually physically copying it around in memory. vmsplice() does the same than splice(), but instead of splicing from fd to fd as splice() does, it splices from a user address range into a file. The idea and first implementation were done by Linus Torvalds, the final implementation by Jens Axboe (email 1), (email 2), (email 3), (email 4), (commit 1), (commit 2), (commit 3)
Introduce the sync_file_range() syscall, due to concerns about extending in non-POSIX-compatible ways the fadvise() interface. Interface: long sync_file_range(int fd, loff_t offset, loff_t nbytes, int flags). This is used to synchronize a file's data to disk, starting at offset and proceeding for nbytes bytes. More details in (this LWN article) (commit)
Add a new scheduler domain for representing multi-core with shared caches between cores. This makes possible to make smarter cpu scheduling decisions on such systems, improving performance greatly for some cases (see commit) (commit)
Lightweight robust futexes: if a process exits prematurely while holding a pthread_mutex_t lock shared with some other process (e.g. yum segfaults or it's kill -9-ed), then waiters for that lock need to be notified that the last owner of the lock exited in some irregular way. This creates a API to fix that Documentation, ABI documentation, (LWN article) (commit 1), (commit 2), (commit 3)
Block queue IO tracing support (blktrace). This allows users to see any traffic happening on a block device queue. In other words, you can get very detailed stadistics of what your disks are doing. User space support tools available in: git://brick.kernel.dk/data/git/blktrace.git (commit)
Cpuset memory spread implementation: Alternative memory allocation policy, 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 (commit 1), (commit 2), (commit 3), (commit 4)
Introduce a user space interface for swsusp (LWN article) (commit), (commit)
Implement /proc/slab_allocators (commit)
New /proc file /proc/self/mountstats, where mounted file systems can export information (configuration options, performance counters, and so on) (commit)

-
CONFIG_UNWIND_INFO: Generates frame unwind information (commit)
Reduce the size of (struct fdtable) to exactly 64 bytes on 32bits platforms, lowering kmalloc() allocated space by 50% (commit)
Optimize select/poll by putting small data sets on the stack instead of using kmalloc for small fd sets, an old optimization from Linux 2.0 (commit)
Deprecate the use of MS_VERBOSE and replace it with MS_SILENT (commit)
Add API for flushing Anon pages (commit)
Add flush_kernel_dcache_page() API (commit)
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 (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 (commit)
unify page_to_pfn(),pfn_to_page() (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) LWN article) (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 (LWN article) (commit)
Permit Dual-MIT/GPL licenses (commit)
CFQ: Seek and async performance tuning (commit), change cfq io context linking from list to tree: Improves performance on setups with many disks (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. The UP->SMP case is useful for CPU hotplug (which may be useful in virtualized environments to hot-add/remove CPUs in virtualized guests in reaction to load changes in the host) (LWN article) (commit)
Make CONFIG_REGPARM enabled by default. With this option, GCC passes the first 3 function parameters in registers. It's a noticable win both for size and for performance, and gcc[34] handles it correctly (commit)
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 (commit)
Increase the variability of the process stack on x86-64 for now. 8 MB is not really very random, use 1GB (or more with larger page sizes) instead(commit)
Allow disabling the "sep" feature (X86_FEATURE_SEP) at boot. This forces use of the int80 vsyscall, useful mainly for testing or benchmarking the int80 vsyscall code (commit)
"make isoimage" support, FDINITRD= support. This adds a "make isoimage" to i386 and x86-64, which allows the automatic creation of a bootable CD image. It also adds an option FDINITRD= to include an initrd of the user's choice in generated floppy- or CD boot images (commit)
