Ah, I thought you wanted to put this in `drivers/gpu/nova-core/num.rs`
like in the previous version.

If it is here instead, then you shouldn't need the
`rust_allowed_features` change anymore, because we already enable
`inline_const` in the `kernel` crate.

Having said that, if you do end up needing it elsewhere, then please
add the other line added by Gary's patch, i.e.:

  +#   - Stable since Rust 1.79.0: `feature(inline_const)`.

Thanks!

Cheers,
Miguel
