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."
