Subject: [PATCH REPOST 3/5] rbd: drop flags parameter from rbd_req_sync_exec()
Date: Thu, 03 Jan 2013 17:19:08 -0600	[thread overview]
Message-ID: <50E611EC.8060301@inktank.com> (raw)
In-Reply-To: <50E61175.7010103@inktank.com>

All callers of rbd_req_sync_exec() pass CEPH_OSD_FLAG_READ as their
flags argument.  Delete that parameter and use CEPH_OSD_FLAG_READ
within the function.  If we find a need to support write operations
we can add it back again.
