Merge branch 'vhost-fixes'
Jason Wang says: ==================== Fix various issue of vhost This series tries to fix various issues of vhost: - Patch 1 adds a missing write barrier between used idx updating and logging. - Patch 2-3 brings back the protection of device IOTLB through vq mutex, this fixes possible use after free in device IOTLB entries. Please consider them for -stable. Changes from V2: - drop dirty page fix and make it for net-next Changes from V1: - silent compiler warning for 32bit. - use mutex_trylock() on slowpath instead of mutex_lock() even on fast path. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
