Message-Id: <1483718362-18147-1-git-send-email-jlayton@redhat.com> Date: Fri, 6 Jan 2017 10:59:22 -0500 From: Jeff Layton <jlayton@...hat.com> To: Al Viro <viro@....linux.org.uk> Cc: linux-fsdevel@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] iov_iter: add missing handling for ITER_KVEC in iov_iter_single_seg_count This seems to currently work by happenstance since kvec and iovec fields basically the same, but it's probably better to make this explicit.
