If you prefer v7, I'm fine with that. For cache issues, I can pull out
the funcs from the tracepoint structure like I posted.

I very much prefer to land this v8 as-is and optimize later.

I still have bpfilter/microkernel patches to finish which were
practically ready two weeks ago and got delayed but this set.
