![]() We need to hold the queue-lock when checking whether we still have a valid unit/port handle for the task management command, i.e whether we can issue this request for this unit/port. If the error recovery is about to close this unit/port, then it competes for the queue-lock. If the close request issued by the error recovery wins, then it is guaranteed that this unit/port has been blocked for other requests.
