Sorry, I thought Greg took all of staging.

A problem with MAINTAINERS is there is no way to tell who applies
patches for a given path vs. anyone else listed. This frequently
happens when the maintainer organization doesn't match the directory
org. If we distinguished this, then it would be quite easy to see when
you've created a patch that needs to be split to different maintainers
(or an explanation why it isn't). Whatever happened with splitting up
MAINTAINERS? If there was a file for each maintainer tree, then it
would be easier to extract that information.

Or maybe we just need to be stricter with the 'M' vs. 'R' tag and 'M'
means that is the person who applies the patch. I don't think many
drivers have their own tree and maintainer except for a few big ones.
