Pull gfs2 updates from Bob Peterson:
 "We've got a lot of patches (39) for this merge window. Most of these
  patches are related to corruption that occurs when journals are
  replayed. For example:

   1. A node fails while writing to the file system.
   2. Other nodes use the metadata that was once used by the failed
      node.
   3. When the node returns to the cluster, its journal is replayed, but
      the older metadata blocks overwrite the changes from step 2.

  Summary:

   - Fixed the recovery sequence to prevent corruption during journal
     replay.

   - Many bug fixes found during recovery testing.

   - New improved file system withdraw sequence.

   - Fixed how resource group buffers are managed.

   - Fixed how metadata revokes are tracked and written.

   - Improve processing of IO errors hit by daemons like logd and
     quotad.

   - Improved error checking in metadata writes.

   - Fixed how qadata quota data structures are managed"
