You're right. Thanks for catching that.
I think it should look like this:

{
int ret = eligible_child(type, pid, options, p);
if (ret <= 0)
return ret;
if (p->exit_state == EXIT_DEAD)
return 0;
/*
* We don't reap group leaders with subthreads.
*/
if (p->exit_state == EXIT_ZOMBIE && !delay_group_leader(p))
return wait_task_zombie(p, options, infop, stat_addr, ru);
/*
* It's stopped or running now, so it might
* later continue, exit, or stop again.
*/
*retval = 0;
if (task_is_stopped_or_traced(p))
return wait_task_stopped(p, options, infop, stat_addr, ru);
return wait_task_continued(p, options, infop, stat_addr, ru);
}
What do you think?


Thanks,
Roland
