I think this part is outside the scope of this patch set. Honestly, I
need to chisel out some time to rewrite the ftrace-design document, as
that's been long needed. But that can come at a later time. I'm
currently rewriting some of it now, so it will be best to not waste
effort to update a document that will soon become stale. ;-)
