This is turning into exactly what I was afraid and I warned it would turn onto:

1. https://git.kernel.org/tip/952df63ef426b21d6da14bb48748f12b0ae2fe36 - we *just* updated it and there's already a new one

2. Random people - not Intel - are going to be sending updates too.

This is a mess waiting to happen. ;-/
