Subject: [PATCH] vhost: make msg padding explicit
Date: Fri, 27 Apr 2018 19:02:05 +0300	[thread overview]
Message-ID: <1524844881-178524-1-git-send-email-mst@redhat.com> (raw)

There's a 32 bit hole just after type. It's best to
give it a name, this way compiler is forced to initialize
it with rest of the structure.
