  Hi Jim I think this "writeback deadlock" should be sent for
  current 3.1 since surly it renders pnfsblock unusable. If you
  feel it has not been tested enough consider submitting it with
  CC: stable@. Because it should hit 3.1.x eventually. No?
  (While at it maybe some of the other clear FIXs above as well
   these that make it unusable)

I did send it to Trond (see the first list above).  If the patches from the
first list don't show up in 3.1 I will send them again with cc: stable.
