Absolutely.

And valid lockdep complaints are a real issue too.

So I don't think there's any question that this should be reverted,
the only question is whether I take the revert directly or get it from
the PM tree.

It does sound like the de_thread() behavior needs more work. Maybe,
for example, we need to make it clear that zapped threads are *not*
frozen, and instead the freezer will wait for them to exit?

Hmm?
