I'm trying to look through these, and finding (as usual) that the
signal handling and exit code is extremely scary from a correctness
and security standpoint.

I really want Oleg to review/ack these. Oleg?

I also would really really want to see the stuff that actually changes
semantics split out.

For example, I feel much less nervous about things like making the
tasklist RCU-safe. So I'd like to see changes like that be separated
out from the much scarier ones. Would that be possible? Hint hint..
