Yeah, I also have something similar (but half-baked) locally, the Q I wanted to
ask is why a separate header? We have already some of tracing headers. Doesn't
suit well?

There is better place for t*.h, i.e. after static_call_types.h.

Btw, have you tried to sort alphabetically the bulk in the kernel.h after
your series. Does it still build? (Just wondering about state of affairs
with the possible cyclic dependencies.)
