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.. ;) > to many, not only kernel developers.

Yeah, I count that as *one flavor* of instrumentation. :) --==_Exmh_1190181478_4811P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFG8LpmcC3lWbTT17ARAlGZAJ9I703zzUtT2NTnZZ26FWPwugi9SACg8Q39 Bvg58hI+TXWqKDO4+BebrbI= =u3GT -----END PGP SIGNATURE----- --==_Exmh_1190181478_4811P--
