Please review. Changes from V2: - use seqlck helper to synchronize MMU notifier with vhost worker Changes from V1: - try not use RCU to syncrhonize MMU notifier with vhost worker - set dirty pages after no readers - return -EAGAIN only when we find the range is overlapped with metadata Jason Wang (9): vhost: don't set uaddr for invalid address vhost: validate MMU notifier registration vhost: fix vhost map leak vhost: reset invalidate_count in vhost_set_vring_num_addr() vhost: mark dirty pages during map uninit vhost: don't do synchronize_rcu() in vhost_uninit_vq_maps() vhost: do not use RCU to synchronize MMU notifier with worker vhost: correctly set dirty pages in MMU notifiers callback vhost: do not return -EAGAIN for non blocking invalidation too early Michael S.
