I'm applying this patch to net-next-2.6 for three reasons: 1) it is easily the cleanest and most well done CUBIC patch submission, and they should be rewarded for the quality of this work 2) the only way to get exposure is to merge this now and look out for problems, and yes that means keeping it the default 3) if there is a problem it's a one line change to revert to previous CUBIC behvaior, by setting hystart to 0, and that's always a safe alternative because that is pretty much what is deployed all over the world right now Thanks!
