Subject: [PATCH net v2 0/2] virtio_net: fix lock warning and unrecoverable state

Patch 1 describes and fixes an issue where dim cannot return to
normal state in certain scenarios.

Patch 2 attempts to resolve lockdep's complaints that holding many
nested locks and when there is a maximum number of queues may also
be problematic, so try to remove the dim_lock.

Changelog

v1->v2:
  Patch(2/2): rephase the commit log.

Heng Qi (2):

  Revert "virtio_net: Add a lock for per queue RX coalesce"
