Hi Wang,

Please try to include the context of what you're replying to in your
messages, reading the above I have to _just remember_ what Zi said, and I'm
old so that's hard now ;)

Please note that mm tests _must_ work without make headers_install being
run.

Your test must not rely upon those.

Thanks, Lorenzo
