Merge tag 'xfs-for-linus-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs

Browse Source 
Pull xfs update from Dave Chinner:
 "There's relatively little change in this update; it is mainly bug
  fixes, cleanups and more of the on-going libxfs restructuring and
  on-disk format header consolidation work.

  Details:
   - more on-disk format header consolidation
   - move some structures shared with userspace to libxfs
   - new per-mount workqueue to fix for deadlocks between nested loop
     mounted filesystems
   - various bug fixes for ENOSPC, stats, quota off and preallocation
   - a bunch of compiler warning fixes for set-but-unused variables
   - various code cleanups"
