A possible solution would be to change the core crate to not divide u64s, but the last time I tried to do that I couldn’t quite figure out how to do formatting without it, maybe I will just open an issue against Rust.
Yeah, I have some context at:
https://github.com/Rust-for-Linux/linux/issues/2 -> feature(compiler_builtins) and a way to avoid certain intrinsics (f32, f64, i128, u128 and 64-bit divisions/modulos).
We have discussed it at some points with upstream Rust (including related discussions about having more `cfg`s in `core` or a `cfg(linux_kernel)` etc.). I don't think we have an open issue concretely for it, apart from the Clippy one to flag the use the use of the 64-bit division, but if you open a more general one with some details, that would be great.
Thanks!
