From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chuck Lever Subject: [PATCH v2 07/12] rpcrdma: Add RPCRDMA_HDRLEN_ERR Date: Thu, 18 Feb 2016 12:30:51 -0500 Message-ID: <20160218173051.14009.58818.stgit@manet.1015granger.net> References: <20160218172449.14009.47311.stgit@manet.1015granger.net> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <20160218172449.14009.47311.stgit-FYjufvaPoItvLzlybtyyYzGyq/o6K9yX@public.gmane.org> Sender: linux-nfs-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-nfs-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: linux-rdma@vger.kernel.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.
