Are you referring to this discussion?
https://lore.kernel.org/rust-for-linux/DDK4KADWJHMG.1FUPL3SDR26XF@kernel.org/
If so, I have posted something along those lines:
https://lore.kernel.org/rust-for-linux/20251029-nova-as-v3-4-6a30c7333ad9@nvidia.com/
We planned to have it stew in Nova for a bit, but I don't mind moving
this to the core code if you think that looks good enough.
