[PATCH 0/3] rbd: header read/refresh improvements

[Douglas Fuller <dfuller@redhat.com>]

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.
