Subject: [PATCH V4 0/9] Fixes for metadata accelreation

Hi all:

This series try to fix several issues introduced by meta data
accelreation series. Please review.

Changes from V3:
- remove the unnecessary patch

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
