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

Pull gfs2 updates from Steven Whitehouse:
 "The main feature of interest this time is quota updates.  There are
  some clean ups and some patches to use the new generic lru list code.

  There is still plenty of scope for some further changes in due course -
  faster lookups of quota structures is very much on the todo list.
  Also, a start has been made towards the more tricky issue of using the
  generic lru code with glocks, but that will have to be completed in a
  subsequent merge window.

  The other, more minor feature, is that there have been a number of
  performance patches which relate to block allocation.  In particular
  they will improve performance when the disk is nearly full"
