So kernel/bpf/ patches are usually going via netdev tree as main development happens there and to avoid cross tree conflicts, etc. Thus, please Cc also netdev in the next iterations. Maybe when these patches are in a perfect shape at some point, perf folks provide their Acked-by(s) to the series to give their consent, and then this should go via net-next? Or will this be organized differently?
