    make do_notify_parent() __must_check, update the callers · 86773473

    Change other callers of do_notify_parent() to check the value it
    returns, this makes the subsequent task_detached() unnecessary.
    Mark do_notify_parent() as __must_check.
    Use thread_group_leader() instead of !task_detached() to check
    if we need to notify the real parent in wait_task_zombie().
    Remove the stale comment in release_task(). "just for sanity" is
    no longer true, we have to set EXIT_DEAD to avoid the races with
