Ahh.. Where I come from, "Instrumentation" includes *all* the code that doesn't
actually *do* the work, but exists solely so you can tell what the code is
doing - so almost everything on the i386/x86_64 "Kernel Hacking" menu counts
as "instrumentation" in my book.

Now if we're talking about the features provided by one specific *instance*
of instrumentation code, I can buy that too - but I think that help text
needs to be clear on what is included under "debugging"

(I'd settle for "If you're trying to debug the kernel itself, go see the
Kernel Hacking menu" or similar.. ;)

Ahh, LTT. *that* I recognize.  Yeah, I count that as *one flavor* of
instrumentation. :)
