The simple HT support is a very small patch (see http://www.FreeBSD.org/~jhb/patches/htt.patch) and is something that several people/companies that use 4.x need. > We should stop moving new features into 4 for 2 reasons, a) I've always > been against feature development of -stable, but b) we need to encourage > take-up of our latest branch and the less "modern" 4 is the more likely > people will be to migrate around 5.2.

Also, I don't know about you, but where I work we aren't going to be using 5.x in production until it gets a lot better. Both SMPng and KSE (and other things like new schedulers) are very ambitious projects that take a while to get done. There is no magic waving of arms that is going to solve those problems in the next 3 months. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
