AFAIK, exit_signal = -1 means that the parent don't want to be signalled, like what happenes when using CLONE_THREAD. But it's even signalled in that case (after issuing a BUG): BUG_ON(leader->exit_signal == -1); do_notify_parent(leader, leader->exit_signal); > do_notify_parent() checks if the parent wants to get informed about the > child states. > Yes it does the check but it notifies the given task_struct anyway: BUG_ON(sig == -1); [ Continue parent notification normally ] -- Ahmed S.
