I'm not necessarily against the rename but you can't, or at least shouldn't,
modify the cpu affinity of any workqueue worker. You don't know what that
worker is going to be executing even at the moment when the cpu affinity
change is committed, let alone in any future. Can you please drop that part
from the patch description? It doesn't make a lot of sense.
