Well, I need to think more. SIGNAL_GROUP_DUMPING is not that simple. If we want to use it in recalc_sigpending(), we can only set it after coredump_wait() succeeds. And we need some changes in send_signal()->complete_signal() anyway, to make sure SIGKILL does wakeup even if SIGNAL_GROUP_EXIT. Sorry for delay, will try to make patches soon ;) Oleg. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
