Subject: [PATCH 08/12] rbd: drop rbd_req_sync_exec() "ver" parameter
Date: Thu, 19 Jul 2012 16:08:48 -0500	[thread overview]
Message-ID: <50087760.5070204@inktank.com> (raw)
In-Reply-To: <500874F5.4090205@inktank.com>

The only place that passes a version pointer to rbd_req_sync_exec()
is in rbd_header_add_snap(), and that spot ignores the result.

The only thing rbd_req_sync_exec() does with its "ver" parameter is
pass it directly to rbd_req_sync_op().  So we can just use a null
pointer there, and drop the "ver" parameter to rbd_req_sync_exec().
