What we want here is two fold:

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?
Oops, this causes recursive dependency error :-(
kernel/trace/Kconfig:90:error: found recursive dependency: TRACING ->
EVENT_TRACING -> EVENT_PROFILE -> KPROBE_TRACER -> GENERIC_TRACER -> TRACING
At this time, this kind of weak dependency may not supported by Kbuild yet.
Thank you,
