Merge tag 'xfs-for-linus-3.15-rc5' of git://oss.sgi.com/xfs/xfs

Pull xfs fixes from Dave Chinner:
 "The main fix is adding support for default ACLs on O_TMPFILE opened
  inodes to bring XFS into line with other filesystems.  Metadata CRCs
  are now also considered well enough tested to be fully supported, so
  we're removing the shouty warnings issued at mount time for
  filesystems with that format.  And there's transaction block
  reservation overrun fix.

  Summary:
   - fix a remote attribute size calculation bug that leads to a
     transaction overrun
   - add default ACLs to O_TMPFILE files
   - Remove the EXPERIMENTAL tag from filesystems with metadata CRC
     support"
