other info that might help us debug this:

Chain exists of:
  &mm->mmap_lock --> &q->q_usage_counter(io)#66 --> &q->debugfs_mutex

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(&q->debugfs_mutex);
                               lock(&q->q_usage_counter(io)#66);
                               lock(&q->debugfs_mutex);
  rlock(&mm->mmap_lock);
