This allows rr to work with perf_event_paranoid == 2 starting with 6.10, where rr previously required perf_event_paranoid == 1.

That’s quite nice, I remember having to fight my school’s sysadmins because of this requirement when begging them to install rr on the students’ machines.

Thanks for improving rr. I rely on rr heavily. It’s an invaluable too navigate the massive LLVM codebase (by debugging a lit test).
