I guess I will have to double-check that the slub corruption is gone
still with that fixed.

So I'm not getting any warnings now from SLUB debugging. So the
original bug seems to not have re-surfaced, and the registration bug
is gone, so now the unregistration doesn't warn about anything either.

But I only rebooted three times.

Looks good to me, I applied it to my tree with your signoff and will
send you a pull request right now.

I'm still seeing:
