which may have answers for most questions.

Hi H.J.,

I know you're not super familiar with our kernel development process,
which might be why you've been repeatedly referring folks to your
presentations.  Our efforts here on the kernel mailing list are to
ensure that we have a nice standalone changelog in the kernel forever.
Great as your presentation might be, it isn't a part of the changelog.

I'm not asking these questions because I need them explained to me.  I'm
asking because I need Yu-cheng to ensure he has the answers in his
changelog when the patches are merged.
