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."
