Re: [PATCH] workqueue: Fix NULL current_pwq deref in flush dependency check

[Tejun Heo]

Applied to wq/for-7.3-fixes.

- is_chained_work() has the same problem. It dereferences
  worker->current_pwq after checking only worker. It is only reached when
  queueing on a draining or destroying workqueue, but a kworker outside a
  work item would crash there the same way. Can you send a fix for that
  one too?

Thanks.
