    perf augmented_raw_syscalls: Augment sockaddr arg in 'connect' · 212b9ab6
    Arnaldo Carvalho de Melo authored
    We already had a beautifier for an augmented sockaddr payload, but that
    was when we were hooking on each syscalls:sys_enter_foo tracepoints,
    since now we're almost doing that by doing a tail call from
    raw_syscalls:sys_enter, its almost the same, we can reuse it straight
    away.
