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

Pull gfs2 updates from Steven Whitehouse:
 "This must be about the smallest merge window patch set ever for GFS2.
  It is probably also the first one without a single patch from me.
  That is down to a combination of factors, and I have some things in
  the works that are not quite ready yet, that I hope to put in next
  time around.

  Returning to what is here this time...  we have 3 patches which fix
  various warnings.  Two are bug fixes (for quotas and also a rare
  recovery race condition).  The final patch, from Ben Marzinski, is an
  important change in the freeze code which has been in progress for
  some time.  This removes the need to take and drop the transaction
  lock for every single transaction, when the only time it was used, was
  at file system freeze time.  Ben's patch integrates the freeze
  operation into the journal flush code as an alternative with lower
  overheads and also lands up resolving some difficult to fix races at
  the same time"
