[PATCH] futex_find_get_task(): remove an obscure EXIT_ZOMBIE check
futex_find_get_task:
if (p->state == EXIT_ZOMBIE || p->exit_state == EXIT_ZOMBIE)
return NULL;
I can't understand this. First, p->state can't be EXIT_ZOMBIE. The
->exit_state check looks strange too. Sub-threads or tasks whose ->parent
ignores SIGCHLD go directly to EXIT_DEAD state (I am ignoring a ptrace
case). Why EXIT_DEAD tasks should be ok? Yes, EXIT_ZOMBIE is more
important (a task may stay zombie for a long time), but this doesn't mean
we should explicitely ignore other EXIT_XXX states.
