And it's likely to miss lots of things you'll probably want, sooner or later. And backporting such far is anything but practical. (I recently had a client who asked me to backport recent BT features onto some old 3.15 vendor kernel - that would have taken years to get anythings stable). Seriously, don't try to use such old code in production systems. It's better to rebase your individual customizations onto recent mainline releases. --mtx -- Enrico Weigelt, metux IT consult Free software and Linux embedded engineering info@xxxxxxxxx -- +49-151-27565287
