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

Pull GFS2 updates from Steven Whitehouse:
 "There is not a whole lot of change this time - there are some further
  changes which are in the works, but those will be held over until next
  time.

  Here there are some clean ups to inode creation, the addition of an
  origin (local or remote) indicator to glock demote requests, removal
  of one of the remaining GFP_NOFAIL allocations during log flushes, one
  minor clean up, and a one liner bug fix."

* git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw:
  GFS2: Flush work queue before clearing glock hash tables
  GFS2: Add origin indicator to glock demote tracing
  GFS2: Add origin indicator to glock callbacks
  GFS2: replace gfs2_ail structure with gfs2_trans
  GFS2: Remove vestigial parameter ip from function rs_deltree
  GFS2: Use gfs2_dinode_out() in the inode create path
  GFS2: Remove gfs2_refresh_inode from inode creation path
  GFS2: Clean up inode creation path
