No, it sounds like there's nothing here I need. Why do I need to review any
code that is not going to improve my subsystem?

Like I said. I don't see the improvement. I hate changes for changes sake
alone. If there was a real improvement to the system, then I would make the
time to look at it. But currently, the only thing I get is that you want
this code in. And that's not a high enough bar.

As I stated before, and have given talks about. Changes are pulled into
Linux, they are never pushed.
