I wonder if it wouldn't be too much trouble to write at least a brief
overview document under Documentation/ describing what this is all
about? Even as follow-up. People seeing the patch series have the
benefit of the cover letter and the commit messages, but that's hardly
documentation.

We have all these great frameworks and tools but their discoverability
to kernel developers isn't always all that great.

Jani.
