You can write arbitrary kernel modules in Rust, I think there are a few floating around. Core kernel will never have Rust in it, and that is a correct decision

You can write arbitrary kernel modules in Rust, I think there are a few floating around. Core kernel will never have Rust in it, and that is a correct decision. Linux and C have a long history of just working, and there is value in making sure that C code you write is correct and explicitly thinking about memory and what gets modified where. Correct coding is more than just memory safety, and compilers can't check everything for you.
