Looks ok to me. > And, the "->parent->signal->flags & SIGNAL_GROUP_EXIT" check in exit_notify() > is not right. SIGNAL_GROUP_EXIT can mean exec(), not exit_group(). This means > ptracer can lose a ptraced zombie on exec(). Minor problem, but still the bug. This bug never happens because this check is only in the now-impossible ptrace-same-group case. The code can certainly go.
