4.14-stable review patch. If anyone has any objections, please let me know.
From: Jason Wang <jasow...@redhat.com>
[ Upstream commit 4cd879515d686849eec5f718aeac62a70b067d82 ]
We don't stop device before reset owner, this means we could try to
serve any virtqueue kick before reset dev->worker. This will result a
warn since the work was pending at llist during owner resetting. Fix
this by stopping device during owner reset.
Fixes: 3a4d5c94e9593 ("vhost_net: a kernel-level virtio server")
