Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux 

Resolved conflicts:
  fs/xfs/xfs_trans_priv.h:
    - deleted struct xfs_ail field xa_flags
    - kept field xa_log_flush in struct xfs_ail
  fs/xfs/xfs_trans_ail.c:
    - in xfsaild_push(), in XFS_ITEM_PUSHBUF case, replaced
      "flush_log = 1" with "ailp->xa_log_flush++"
