[Jukka Ruohonen <jruohonen%iki.fi@localhost>]

        Note: There was a bad value `sw-big' for the field `Class'.
        It was set to the default value of `sw-bug'.

>Description:

From IEEE Std 1003.1-2008:

    The sched_rr_get_interval() function SHALL fail if:

    [ESRCH]
        No process can be found corresponding to that specified by pid.

Yet

int
/*ARGSUSED*/
sched_rr_get_interval(pid_t pid, struct timespec *interval)
{

        interval->tv_sec = 0;
        interval->tv_nsec = sysconf(_SC_SCHED_RT_TS) * 1000;
        return 0;
}


>How-To-Repeat:

Pass an invalid PID.

>Fix:

Check for valid PID or forget this.
