OK, so back to square one: why am I supposed to do all this work for something that will likely slow things slightly down and, at best, doesn't hurt performance? The old set up works great and as far as I'm concerned, is not broken. Don't get me wrong. I'm willing to invest time to switch to the new setup, but I'd like to have a good reason before doing so. That's not asking for too much, is it? --david - 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/
