We are using rtkit 0.11. I fully agree with the patch as far as setting the values correct in the first place. I was just asking about the need to backport this to existing installations. At least on openSUSE I don't believe we need to do that as the incorrect values are caught by the check in set_scheduler()

rttime = rtkit_get_rttime_usec_max(bus);
r = getrlimit(RLIMIT_RTTIME, &rl);
if (r >= 0 && (long long) rl.rlim_max > rttime) {
    pa_log_info("Clamping rlimit-rttime to %lld for RealtimeKit\n", rttime);
    rl.rlim_cur = rl.rlim_max = rttime;
    ...
