Cool. Thanks for this - looks pretty similar to the systemtap stuff we use, but compile times are faster here. I wonder if bpftrace can do the "guru" things that systemtap can, like modify the stack and memory. Seems it works with gcc too, just needed CONFIG_DEBUG_INFO_BTF=y. I will play with it a bit. Ben
