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

Pull GFS2 updates from Steven Whitehouse:
 "This is one of the smallest collections of patches for the merge
  window for some time.  There are some clean ups relating to the
  transaction code and the shrinker, which are mostly in preparation for
  further development, but also make the code much easier to follow in
  these areas.

  There is a patch which allows the use of ->writepages even in the
  default ordered write mode for all writebacks.  This results in
  sending larger i/os to the block layer, and a subsequent increase in
  performance.  It also reduces the number of different i/o paths by
  one.

  There is also a bug fix reinstating the withdraw ack system which
  somehow got lost when the lock modules were merged into GFS2."

* git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw:
  GFS2: Reinstate withdraw ack system
  GFS2: Get a block reservation before resizing a file
  GFS2: Split glock lru processing into two parts
  GFS2: Use ->writepages for ordered writes
  GFS2: Clean up freeze code
  GFS2: Merge gfs2_attach_bufdata() into trans.c
  GFS2: Copy gfs2_trans_add_bh into new data/meta functions
  GFS2: Split gfs2_trans_add_bh() into two
  GFS2: Merge revoke adding functions
  GFS2: Separate LRU scanning from shrinker
