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
