Can you resend this in a format that I can apply it in (hint, read
Documentation/SubmittingPatches and look at the section about
"Signed-off-by:")

Also, when generating your patch, please do it so that I can apply it
with 'patch -p1', as that is what our tools expect.

There's no context for these patches either, which is odd, care to
regenerate it so we can see what functions are being modified?  That way
I can better review this as I think some of your logic can be moved
around a bit to make it simpler overall.

The idea and implementation is great though, thanks for doing this,
