2005-11-02[XFS] Ondisk format extension for extended attributes (attr2). Basically,Nathan Scott
the data/attr forks now grow up/down from either end of the literal area, rather than dividing the literal area into two chunks and growing both upward. Means we can now make much more efficient use of the attribute space, incl. fitting DMF attributes inline in 256 byte inodes, and large jumps in dbench3 performance numbers. It is self enabling, but can be forced on/off via the attr2/noattr2 mount options. SGI-PV: 941645 SGI-Modid: xfs-linux:xfs-kern:23835a Signed-off-by: Nathan Scott <nathans@sgi.com>

2005-11-02[XFS] Introduce two new mount options (nolargeio/largeio) to allowDavid Chinner
filesystems to expose the filesystem stripe width in stat(2) rather than the page cache size. This allows applications requiring high bandwidth to easily determine the optimum I/O size for the underlying filesystem. The default is to report the page cache size (i.e. "nolargeio").

2005-11-02[XFS] write barrier support Issue all log sync operations as orderedChristoph Hellwig
writes. In addition flush the disk cache on fsync if the sync cached operation didn't sync the log to disk (this requires some additional bookeping in the transaction and log code). If the device doesn't claim to support barriers, the filesystem has an extern log volume or the trial superblock write with barriers enabled failed we disable barriers and print a warning. We should probably fail the mount completely, but that could lead to nasty boot failures for the root filesystem. Not enabled by default yet, needs more destructive testing first.

2005-10-29[PATCH] mm: split page table lockHugh Dickins
Christoph Lameter demonstrated very poor scalability on the SGI 512-way, with a many-threaded application which concurrently initializes different parts of a large anonymous area. This patch corrects that, by using a separate spinlock per page table page, to guard the page table entries in that page, instead of using the mm's single page_table_lock. (But even then, page_table_lock is still used to guard page table allocation, and anon_vma allocation.) In this implementation, the spinlock is tucked inside the struct page of the page table page: with a BUILD_BUG_ON in case it overflows - which it would in the case of 32-bit PA-RISC with spinlock debugging enabled. Splitting the lock is not quite for free: another cacheline access. Ideally, I suppose we would use split ptlock only for multi-threaded processes on multi-cpu machines; but deciding that dynamically would have its own costs. So for now enable it by config, at some number of cpus - since the Kconfig language doesn't support inequalities, let preprocessor compare that with NR_CPUS. But I don't think it's worth being user-configurable: for good testing of both split and unsplit configs, split now at 4 cpus, and perhaps change that to 8 later. There is a benefit even for singly threaded processes: kswapd can be attacking one part of the mm while another part is busy faulting.

2005-10-28[PATCH] gfp_t: fs/*Al Viro
- ->releasepage() annotated (s/int/gfp_t), instances updated - missing gfp_t in fs/* added - fixed misannotation from the original sweep caught by bitwise checks: XFS used __nocast both for gfp_t and for flags used by XFS allocator. The latter left with unsigned int __nocast; we might want to add a different type for those but for now let's leave them alone. That, BTW, is a case when __nocast use had been actively confusing - it had been used in the same code for two different and similar types, with no way to catch misuses. Switch of gfp_t to bitwise had caught that immediately... One tricky bit is left alone to be dealt with later - mapping->flags is a mix of gfp_t and error indications. Left alone for now.

2005-10-08[PATCH] gfp flags annotations - part 1Al Viro
- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.
