From eb6a388624ec40d9be5c965ad05531ef1b5f4eb3 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Tue, 10 Nov 2020 17:11:20 +0000 Subject: [PATCH] vhost-user-blk-server: depend on CONFIG_VHOST_USER MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit I interpreted CONFIG_VHOST_USER as controlling only QEMU's vhost-user device frontends. However, virtiofsd and contrib/ vhost-user device backends are also controlled by CONFIG_VHOST_USER. Make the vhost-user-blk server depend on CONFIG_VHOST_USER for consistency. Now the following error is printed when the vhost-user-blk server is enabled without CONFIG_VHOST_USER: $ ./configure --disable-vhost-user --enable-vhost-user-blk ... ../meson.build:761:8: ERROR: Problem encountered: vhost_user_blk_server requires vhost-user support Suggested-by: Philippe Mathieu-Daudé Suggested-by: Alex Bennée Signed-off-by: Stefan Hajnoczi Message-Id: <20201110171121.1265142-3-stefanha@redhat.com> Reviewed-by: Michael S.
