These patches don't apply cleanly at all. In the net/ipv4/route.c code we don't initialize the genid to zero, we stick a random value there. And we don't increment it by one on flushes, instead we increment it by a random amount. I wonder what tree these were even against, the differences were so great. -- To unsubscribe from this list: send the line "unsubscribe linux-sctp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
