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

Pull gfs2 fixes from Steven Whitehouse:
 "There are four patches this time.

  The first fixes a problem where the wrong descriptor type was being
  written into the log for journaled data blocks.

  The second fixes a race relating to the deallocation of allocator
  data.

  The third provides a fallback if kmalloc is unable to satisfy a
  request to allocate a directory hash table.

  The fourth fixes the iopen glock caching so that inodes are deleted in
  a more timely manner after rmdir/unlink"
