Merge git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw

Pull GFS2 updates from Steven Whitehouse:
 "There are a few bug fixes for various, mostly very minor corner cases,
  plus some interesting new features.

  The new features include atomic_open whose main benefit will be the
  reduction in locking overhead in case of combined lookup/create and
  open operations, sorting the log buffer lists by block number to
  improve the efficiency of AIL writeback, and aggressively issuing
  revokes in gfs2_log_flush to reduce overhead when dropping glocks."
