Subject: [PATCH v4 07/13] rpcrdma: Add RPCRDMA_HDRLEN_ERR
Date: Mon, 22 Feb 2016 15:41:45 -0500 [thread overview]
Message-ID: <20160222204145.3274.90187.stgit@sisley.1015granger.net> (raw)
In-Reply-To: <20160222203550.3274.82777.stgit@sisley.1015granger.net>
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.
