[PATCH v3 -next 0/2] blk-cgroup: synchoronize blkg creation against policy deactivation

[Yu Kuai]

Changes in V3:
 - grab q_usage_counter in blkg_conf_prep() instead of introducing a
 new mutex.

Changes in V2:
 - rename the patch title
 - instead of checking policy in blkg_create(), using a new solution.

Yu Kuai (2):
  blk-cgroup: don't call blk_mq_freeze_queue() in
    blkcg_deactivate_policy()
  blk-cgroup: synchoronize blkg creation against policy deactivation
