Sure, at least that combination should enable kprobe-tracer forcibly.
Hmm, someone may not want to enables kprobe-tracer. Perhaps,
"default y if (EVENT_PROFILE)" is enough, isn't it?
I guess it should be sufficient yeah. We want to strongly recommend
the kprobe events if we have enabled perf, but we don't want to force
Also in this case we need a verbose runtime report of the lack of this
tracer in debugfs from perf probe if needed.
