Hi, I am currently writing up my dissertation based on dynamic tracing and reducing the learning curve to understanding the UNIX kernel. I used two dynamic tracing technologies (Systemtap and Dtrace) to monitor some virtual machines on a network. Whilst going over my initial review of technologies in the area of dynamic tracing I realised I had underestimated ftrace, and even dismissed it as not being dynamic. However I read hear (http://lwn.net/Articles/343766/) that you were as of July last year trying to introduce a patch that would allow ftrace the ability to dynamically trace. Also it would be completely instrumented from the command line without the need to compile a kernel module al la Systemtap.
My question is do you think Systemtap will be replaced by ftrace in the future if so I feel I may need to include this fact in my updated technology review.
Than you for your time Steve Brown
