From c6db03ea577846a72dc80638f4a70b392c21962f Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 1 Mar 2016 13:06:29 -0500 Subject: [PATCH] rpcrdma: Add RPCRDMA_HDRLEN_ERR 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.
