You get all that seperation for every data structure for free. Think about it a bit. Aren't you going to feel a little bit stupid if you do all this work, one object at a time, and someone can come along and do the whole OS in one swoop? Yeah, I'm spouting crap, it isn't that easy, but it is much easier than the route you are taking. -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm - 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/
