Jason Wang 2b23a36517 vhost: make sure used idx is seen before log in vhost_add_used_n() ... [ Upstream commit 841df92241 ] 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(). Fixes: 8dd014adfe ("vhost-net: mergeable buffers support") Acked-by: Michael S.
