Efforts to get rid of forks are always good.

Could you perhaps elaborate a bit what changes you need
in mainline (ideally separated in "essential" and "nice to
have") and how big the left over patches are?

Or rather how difficult would it be to simply run
the LTT userland on top of the tracing code that is
in mainline, even at loss of some functionality?

Thanks,
