February update

			February has been been busy with development for Linux 3.3, although only
			little new code made it to the development tree yet, mostly a refactor
			of the log grant code. Patch traffic on the mailing list included a rewrite
			of disk quota caching, yielding dramatic performance improvements for systems
			with lots of quotas, a series to make all inode updates and thus all live
			metadata updates transactional. Last but not least a version versions to
			fix a long standing bug in support of the real time subvolume was posted,
			showing that even this long deprecated feature still has a user base.

			On the userspace side development has been quite, with just two fixes to
			xfs_io committed to xfsprogs, while waiting for the long overdue 3.1.8
			release. Xfsdump has been entirely quite this month, again waiting for
			a release, and xfstests saw only two commits either, although there are
			still lots of outstanding patches on the list that haven't been reviewed
			and/or applied.

January update

			January saw the release of Linux 3.2, which as usual included a large
			number of XFS changes, most notably an large speedup for removing files
			that have external attribute blocks, speedups and livelock fixes for
			sync while doing heavy I/O, and large internal cleanups of the inode
			block map handling. The diffstat for XFS in Linux 3.2 is:

			54 files changed, 2414 insertions(+), 2625 deletions(-)

			which is slightly below the average of the last releases.

			In the meantime development for 3.3 went ahead full speed, including
			the removal of the deprecated pre-delaylog logging code, various
			quota cleanups, a shrink of the inode, a great simplification of the file
			write path as well as the usual batch of fixes and cleanups.

			On the userland side xfs_repair saw various major fixes and speedups,
			with few other fixes thrown in, while xfsdump got two commits fixing
			longer standing issues recently reported on the mailing list. For
			xfstests January was an extremely slow month, seeing only two new test cases
			and less than a handful of other updates.

December update

			== XFS status update for December 2011 ==

			December saw further stabilization of the Linux 3.2 release candidates.
			For XFS that meant two important fixes for sync() data integrity, to
			work around issues introduced in the VFS sync code in the past few
			kernel releases. These fixes have also been backported to the 3.0-stable
			release.

			Development for the next merge windows continue in fast pace, although
			only a relatively small amount of patches was merged into the development
			tree for the Linux 3.3 window. The most interesting topic in December
			probably was further development of the SEEK_DATA / SEEK_HOLE support,
			including defining the exact semantics in presence of unwritten extents
			and proper test coverage.

			On the user space side December was fairly quite, with about a handful
			fixes commit to xfsprogs, two new test cases and a couple of fixes in
			xfstests, and no activity in xfsdump.

november update

			== XFS status update for November 2011 ==

			November saw stabilization of the Linux 3.2 release candidates, including
			a few fixes for XFS. In addition a lot of bug fixes were backported to
			the 3.0 long term stable and 3.1-stable releases for users not on
			bleeding edge kernels.

			At the same time development for Linux 3.3 went on at a fast pace, although
			no pages were merged into the development tree yet. The highlights are:

			- further versions of the patches to log all file size updates instead of
			relying the the flaky VM writeback code for them
			- an initial version of SEEK_HOLE/SEEK_DATA support
			- removal of the old non-delaylog logging code, and cleanups resulting
			from the removal
			- large updates for the quota code

			Userspace development was even more busy:

			Xfsprogs saw the rushed 3.1.7 release which contains Debian packaging fixes,
			a polish translation update and a xfs_repair fix. In the meantime a lot of
			xfs_repair fixes were posted but mostly not reviewed and commit yet.

			Xfsdump grew support for using pthreads to write backup streams to multiple
			tapes in parallel, and SGI_XFSDUMP_SKIP_FILE which has been deprecated in
			favor of the nodump flag has finally been removed.
			Xfstests saw an enormous amount of updates. The fsstress tool saw major
			updates to exercise even more system calls, and found numerous bugs in
			all major Linux filesystems, additional ENOSPC tests, a new test for
			btrfs-specific functionality and the usual amount of bug fixes and small
			cleanups. Also a series to clean up the very large filesystem testing,
			including extending the support to ext4 was posted but not committed yet.

October updates

			== XFS status update for October 2011 ==

			October finally saw the delayed release of Linux 3.1, which is a fairly
			boring release as XFS is concerned. In addition to a few bug fixes
			and cleanups the biggest item is an XFS-internal re organization of the
			source files, dropping all sub directories under fs/xfs.

			Due to the long Linux 3.1 release cycle development for 3.3 has already
			started full steam in October while adding a few more small optimization
			and fixes to the development tree for Linux 3.2, and merging that tree
			into mainline.

			Notable items for Linux 3.2 are speedup for parallel O_DIRECT reads and
			writes on high IOPS devices, optimizations for fsync(2) on directories
			and sync(2) latency, as well as further small improvements for metadata
			performance on highly parallel workloads.

			On the user space side xfsprogs saw a few more xfs_repair fixes, as well
			as some updates of mount point handling for the xfs_quota tools, which
			together with the updates from the last months was published in form
			of the xfsprogs 3.1.6 release. This was accompanied by an xfsdump
			3.0.6 release, which does not include any new updates in October, but
			lots of work from the previous month. Xfstests saw two additional
			test cases and various fixes, and it's first versioned release ever.

September update

			== XFS status update for September 2011 ==

			August saw further release candidates of Linux 3.1, which had been
			completely uneventful with just a single small regression fix being
			merged.

			In the meantime developments for the Linux 3.2 kernel went on with the merge
			of a large series that completely refactors the XFS-internal xfs_bmapi
			interfaces for simpler interfaces and less stack usage, as well as various
			smaller cleanups and fixes.

			September also was a very busy month for userspace development. In xfsprogs
			we saw various error handling fixes to libxcmd, libxfs, mkfs.xfs, xfs_quota
			and xfs_repair, xfsdump saw a few smaller changes finishing up the large
			work done in August. Xfstests saw 4 new test cases contributed from
			various developers, and the usual handful of bug fixes.
