[PATCH V2 0/2] block: fix queue freeze and cleanup

[Ming Lei]

Hi Jens,

The 1st patch runs queue in blk_freeze_queue_start() for fixing one
regression by 055f6e18e08f("block: Make q_usage_counter also track legacy
requests").

The 2nd patch drians blkcg part of request_queue for both blk-mq and
legacy, which can be a fix on blk-mq's queue cleanup.

V2:
        - follow Bart's suggestion to use run queue instead of drain queue
        - drians blkcg part of request_queue for blk-mq

thanks,
Ming

  block: run queue before waiting for q_usage_counter becoming zero
  block: drain blkcg part of request_queue after queue is frozen
