Note, I had a different tree checked out, so I didn't have the source
available without digging through my email.

OK, I thought we had a rcu_dereference_notrace() that did checks and
thought that this followed suit, but it appears there is no such call.
That's where my confusion was.

Sure, I'll nuke the notrace() portion, thanks.

Also, I've applied 1-3, since 4 and 5 looks to be getting a remake, I'm
going to remove them from my queue. Please fold the SPDX patch into 5.

Thanks!
