Subject: rbd: kill rbd_req_sync_op() snapc and snapid parameters
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=2110047b48aab4e71f17ba5f0c2aef34754e3452;p=ceph-client.git

rbd: kill rbd_req_sync_op() snapc and snapid parameters

The snapc and snapid parameters to rbd_req_sync_op() always take
the values NULL and CEPH_NOSNAP, respectively.  So just get rid
of them and use those values where needed.
