Dynamic probes with ftraceDynamic probes with ftracePosted Jul 30, 2009 2:08 UTC (Thu) by fuhchee (subscriber, #40059)Parent article: Dynamic probes with ftrace It is, in fact, conceivable that tools like SystemTap could move over to this mechanism once it's merged Yes, to some extent. that would allow SystemTap to share more of the low-level ftrace plumbing Yes, to some extent. and get it closer to working with unpatched mainline kernels. No. This part of systemtap has worked fine with unpatched mainline kernels since the beginning.

Dynamic probes with ftrace Posted Jul 30, 2009 11:24 UTC (Thu) by fuhchee (subscriber, #40059) [Link] Sorry to self-reply, but:... and get it closer to working with unpatched mainline kernels Makes it sound as if this was some sort of future aspiration. That's wrong: systemtap has essentially always worked with unpatched mainline kernels. (An issue that confuses some is that the user-space probing extensions require utrace. If you don't use that extension in your script, it does not matter.)
