other info that might help us debug this:

Chain exists of:
  fs_reclaim --> &q->q_usage_counter(io)#71 --> &q->blkcg_mutex

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&q->blkcg_mutex);
                               lock(&q->q_usage_counter(io)#71);
                               lock(&q->blkcg_mutex);
  lock(fs_reclaim);
