The difference here is that we basically > add a syscall parameter as a global option. sure. I only disagreed about not touching older flags. --effective should be local. If follow up patch means 90% rewrite then revert is better. If it's 10% fixup then it's different story. Takshak, could you check which way is cleaner? Revert and new patch or follow up fix? But bpftool doesn't have a way to do local, no? so it's kinda new feature and other flags should become local too. hence it feels more like follow up. Just my .02
