From 3cc36f6e34bd2d92d23be7b598ba5e639c47b01a Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Wed, 3 Aug 2016 07:18:51 +0300 Subject: [PATCH] virtio: fix error handling for debug builds On error, virtqueue_add calls START_USE but not END_USE. Thankfully that's normally empty anyway, but might not be when debugging. Fix it up. Signed-off-by: Michael S.
