Pull Ceph fixes from Sage Weil:
 "Yes, this is a much larger pull than I would like after -rc1.  There
  are a few things included:

   - a few fixes for leaks and incorrect assertions
   - a few patches fixing behavior when mapped images are resized
   - handling for cloned/layered images that are flattened out from
     underneath the client

  The last bit was non-trivial, and there is some code movement and
  associated cleanup mixed in.  This was ready and was meant to go in
  last week but I missed the boat on Friday.  My only excuse is that I
  was waiting for an all clear from the testing and there were many
  other shiny things to distract me.

  Strictly speaking, handling the flatten case isn't a regression and
  could wait, so if you like we can try to pull the series apart, but
  Alex and I would much prefer to have it all in as it is a case real
  users will hit with 3.10."
