Subject: [PATCH V3 00/10] Fixes for metadata accelreation
Hi all:
This series try to fix several issues introduced by meta data
accelreation series. 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. Tsirkin (1):
vhost: disable metadata prefetch optimization
