XFS status update for February 2012

[Christoph Hellwig]

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.
