If you have a chance, please review the series.
This series doesn't really touch anything I maintain, but the general appraoch seems sane to me. I like the first patch that ensures structures are passed by reference. The rest is all tracepoint/bpf glue and I never really got into the bpf internals, so I don't think I've got anything useful to say there.
