this time. There is a set of patches to improve performance in relation to
 block reservations. Some correctness fixes for fallocate, and an update
 to the freeze/thaw code which greatly simplyfies this code path. In
 addition there is a set of clean ups from Al Viro too.

Merge tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw

Pull GFS2 update from Steven Whitehouse:
 "In contrast to recent merge windows, there are a number of interesting
  features this time:

  There is a set of patches to improve performance in relation to block
  reservations.  Some correctness fixes for fallocate, and an update to
  the freeze/thaw code which greatly simplyfies this code path.  In
  addition there is a set of clean ups from Al Viro too"

* tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw:
  GFS2: gfs2_atomic_open(): simplify the use of finish_no_open()
  GFS2: gfs2_dir_get_hash_table(): avoiding deferred vfree() is easy here...
  GFS2: use kvfree() instead of open-coding it
  GFS2: gfs2_create_inode(): don't bother with d_splice_alias()
  GFS2: bugger off early if O_CREAT open finds a directory
  GFS2: Deletion of unnecessary checks before two function calls
  GFS2: update freeze code to use freeze/thaw_super on all nodes
  fs: add freeze_super/thaw_super fs hooks
  GFS2: Update timestamps on fallocate
  GFS2: Update i_size properly on fallocate
  GFS2: Use inode_newsize_ok and get_write_access in fallocate
  GFS2: If we use up our block reservation, request more next time
  GFS2: Only increase rs_sizehint
  GFS2: Set of distributed preferences for rgrps
  GFS2: directly return gfs2_dir_check()
