I'm ok with this series that adds explanations for why you care and
what bpf does that makes it valid.

So this one you can put in the bpf tree.

Or, if you want me to just apply it as a series, I can do that too, I
just generally assume that when there's a git tree I usually get
things from, that's the default, so then it needs ot be a very loud
and explicit "Linus, can you apply this directly".
