Jason Wang 04a1c4080c vhost: make sure used idx is seen before log in vhost_add_used_n() ... [ Upstream commit 841df922417eb82c835e93d4b93eb6a68c99d599 ] We miss a write barrier that guarantees used idx is updated and seen before log. This will let userspace sync and copy used ring before used idx is update. Fix this by adding a barrier before log_write().
