Support multiple class op calls in one ceph_msg and consolidate rbd header
read and refresh processes to use this feature to reduce the number of
ceph_msgs sent for that process. Refresh features on header refresh and
begin returning EIO if features have changed since mapping.
Douglas Fuller (3):
ceph: support multiple class method calls in one ceph_msg
rbd: combine object method calls in header refresh using fewer
ceph_msgs
rbd: re-read features during header refresh and detect changes.
