Getting rid of the notifier_block is definitely right, that should not
be there anymore.
I'm curious with the num_possible -> num_online change. This should be
handled by blk-mq, so no worries there. But how did it trigger the unset
CPU in the run mask? Ran into the same issue here on a different test
case, just curious if you looked into this.
