Hi Frank, I was wondering. I am going to try to work with systemtap with a kernel.org 2.6.25.x kernel. My understanding is that neither utrace or uprobes is in there. I did clone systemtap git, but it doesn't look like there are any kernel patches in there. Roland's utrace kernel patches stop at 2.6.24. Please advise me?
