Yes I could do it, but only if it would be interesting for others too. I won't spend time on something that will be totally rejected in the end... My thought was (dispite performance loss), you can probably enable tracing on the fly, or just have another LTT aware kernel on stand-by. Every know and then it would really be helpful to know exactly what's going on in the background. But I haven't tried LTT yet, so I don't have a clue how it will affect performance and/or other stuff. There is a patch for kernel 2.4.16 that only has one reject when applied to 2.4.18, and that is for the s390 arch. -- Regards // Oden Eriksson
