I guess that could be done too, but is there anything wrong with my
current solution? Or is it just too hacky? How would one check if
something exists in a file or not? Say, I want to detect if
preemptirqsoff tracer exists or not, and that only happens if I do a
grep of current_tracer (I have tests coming that will need to do that)?
