Merge tag 'for-linus-v3.11-rc1-2' of git://oss.sgi.com/xfs/xfs

Pull more xfs updates from Ben Myers:
 "Here are a fix for xfs_fsr, a cleanup in bulkstat, a cleanup in
  xfs_open_by_handle, updated mount options documentation, a cleanup in
  xfs_bmapi_write, a fix for the size of dquot log reservations, a fix
  for sgid inheritance when acls are in use, a fix for cleaning up
  quotainfo structures, and some more of the work which allows group and
  project quotas to be used together.

  We had a few more in this last quota category that we might have liked
  to get in, but it looks there are still a few items that need to be
  addressed.

   - fix for xfs_fsr returning -EINVAL
   - cleanup in xfs_bulkstat
   - cleanup in xfs_open_by_handle
   - update mount options documentation
   - clean up local format handling in xfs_bmapi_write
   - fix dquot log reservations which were too small
   - fix sgid inheritance for subdirectories when default acls are in use
   - add project quota fields to various structures
   - fix teardown of quotainfo structures when quotas are turned off"

* tag 'for-linus-v3.11-rc1-2' of git://oss.sgi.com/xfs/xfs:
  xfs: Fix the logic check for all quotas being turned off
  xfs: Add pquota fields where gquota is used.
  xfs: fix sgid inheritance for subdirectories inheriting default acls [V3]
  xfs: dquot log reservations are too small
  xfs: remove local fork format handling from xfs_bmapi_write()
  xfs: update mount options documentation
  xfs: use get_unused_fd_flags(0) instead of get_unused_fd()
  xfs: clean up unused codes at xfs_bulkstat()
  xfs: use XFS_BMAP_BMDR_SPACE vs. XFS_BROOT_SIZE_ADJ
