Merge git://git./linux/kernel/git/steve/gfs2-3.0-fixes

Pull gfs2 fixes from Steven Whitehouse:
 "Out of these five patches, the one for ensuring that the number of
  revokes is not exceeded, and the one for checking the glock is not
  already held in gfs2_getxattr are the two most important.  The latter
  can be triggered by selinux.

  The other three patches are very small and fix mostly fairly trivial
  issues"
