Hi Sasha,

I feel like we need to take a step back here and consider some of the
non-technical consqeuences of this change.

Firstly, there is no doubt whatsoever that, were this series to land, there
would be significant press which would amount to (whether you like it or
not) 'Linux kernel welcomes AI patches'.

I don't feel that a change of this magnitude which is likely to have this
kind of impact should be RFC'd quietly and then, after a weekend, submitted
ready to merge.

This change, whether you like it or not - amounts to (or at the very least,
certainly will be perceived to be) kernel policy. And, AFAIK, we don't have
an AI kernel policy doc yet.

So to me:

- We should establish an official kernel AI policy document.

- This should be discussed at the maintainers summit before proceeding.

In addition, it's concerning that we're explicitly adding configs for
specific, commercial, products. This might be seen as an endorsement
whether intended or not.

Thanks, Lorenzo
