other info that might help us debug this:

Chain exists of:
  &sb->s_type->i_mutex_key#9 --> (wq_completion)"dio/%s"sb->s_id --> (work_completion)(&dio->complete_work)

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock((work_completion)(&dio->complete_work));
