other info that might help us debug this:

Chain exists of:
  &q->elevator_lock --> fs_reclaim --> &q->q_usage_counter(io)#23

 Possible unsafe locking scenario:

other info that might help us debug this:

Chain exists of:
  &q->elevator_lock --> fs_reclaim --> &q->q_usage_counter(io)#23

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&q->q_usage_counter(io)#23);
                               lock(fs_reclaim);
                               lock(&q->q_usage_counter(io)#23);
  lock(&q->elevator_lock);
