Merge tag 'xfs-for-linus-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs

Pull xfs updates from Dave Chinner:
 "There isn't a whole lot to this update - it's mostly bug fixes and
  they are spread pretty much all over XFS.  There are some corruption
  fixes, some fixes for log recovery, some fixes that prevent unount
  from hanging, a lockdep annotation rework for inode locking to prevent
  false positives and the usual random bunch of cleanups and minor
  improvements.

  Deatils:

   - large rework of EFI/EFD lifecycle handling to fix log recovery
     corruption issues, crashes and unmount hangs

   - separate metadata UUID on disk to enable changing boot label UUID
     for v5 filesystems

   - fixes for gcc miscompilation on certain platforms and optimisation
     levels

   - remote attribute allocation and recovery corruption fixes

   - inode lockdep annotation rework to fix bugs with too many
     subclasses

   - directory inode locking changes to prevent lockdep false positives

   - a handful of minor corruption fixes

   - various other small cleanups and bug fixes"
