Hi, I’v started to implement the proc filesystem abstractions in rust, as I want to use it for a driver written in rust. Currently this requires some rust code that is only in the rust branch, so does not apply onto 6.2-rc2. My current work can be found here: https://github.com/Rust-for-Linux/linux/pull/948 I plan to send a proper RFC patch, once I’v got a driver dependent on that, to make sure the abstractions are actually useful and correctly designed.
