Subject: [PATCH v5 08/14] rpcrdma: Add RPCRDMA_HDRLEN_ERR
Date: Tue, 01 Mar 2016 13:06:29 -0500 [thread overview]
Message-ID: <20160301180629.2492.33947.stgit@klimt.1015granger.net> (raw)
In-Reply-To: <20160301180337.2492.4255.stgit-Hs+gFlyCn65vLzlybtyyYzGyq/o6K9yX@public.gmane.org>
Error headers are shorter than either RDMA_MSG or RDMA_NOMSG.
Since HDRLEN_MIN is already used in several other places that would
be annoying to change, add RPCRDMA_HDRLEN_ERR for the one or two
spots where the shorter length is needed.
