From 86d4b0618495faf58ef5e698b3c8ea76e82b54d6 Mon Sep 17 00:00:00 2001 From: Tiwei Bie Date: Mon, 29 Oct 2018 13:28:04 +0800 Subject: [PATCH] net/virtio-user: do not make vhost channel non-block There is no need to make the vhost user channel nonblock, and making it nonblock will make vhost_user_read() fail with EAGAIN when vhost messages need a reply.
