[openstack-dev] [qa][cinder] critical fix for ceph job

I just posted a critical fix the ceph job [1]. I'm anxious to get this landed so I can start working on the other intermittent failures in the gate. Any feedback is much appreciated. [1] https://review.openstack.org/#/c/454321/ -- Jon __

[openstack-dev] Proposal for instance-level snapshots in Nova
