Not generally, but I am not sure we want a per signal_struct idr ;) Really that should be clearly explained in the changelog, so that buggy applications can have a clue of what happened. When we changed UDP source port selection being random instead of sequential, maybe this broke some applications. That was an implementation choice (with security impact). -- 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/
