Hi Sage,

I've seen a couple Redmine tickets on this (eg
http://tracker.ceph.com/issues/9854 ,
http://tracker.ceph.com/issues/10956). It's not totally clear to me
which of the 70+ unreleased commits on the firefly branch fix this
librbd issue.  Is it only the three commits in
https://github.com/ceph/ceph/pull/3410 , or are there more?
