Agreed. I need to push that up in priority in my todo list.

Getting ebpf functionality into tracing could also help filtering and
such, which is still done with tree logic.

Anyway, I would like to get people together in discussing some of these
enhancements at ksummit as well. How to load ebpf into ftrace is another
ABI issue that we need to do right, otherwise that could bite us years
from now.
