So, the problem with the proposed patch is that pwq may still be in use by
then (due to async freeing) and thus can't be freed immediately. I still
don't understand why KASAN is triggering there. I tried to repro by
introducing a pwq alloc failure but couldn't. Can you please share the
repro?

Thanks.
