The few odd drivers are nbd, jffs2 and the usb mass storage gadget. All of these have in common that they try to handle signals in a kernel thread (which we don't even allow by default), and that they ignore the siginfo. I think they could mostly be replaced by an addition to the kthread API to allow a kthread to be killed by signals for legacy reasons. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
