We're talking past each other. I'm not saying copy_workqueue_attrs()
shouldn't copy no_numa. I'm saying get_unbound_pool() should clear
no_numa so that pools don't have random no_numa settings.

Why would apply_workqueue_attrs() modify no_numa when it *is* dealing
with an actual workqueue attr. I've been talking about
get_unbound_pool() not apply_workqueue_attrs() the whole time.

Please update the patch to add no_numa clearing to get_unbound_pool()
and explain what's going on.
