Linus Torvalds: Rust for the Kernel Could Possibly Be Merged for Linux 5.20
I like Rust and I'd love to see it in the Linux kernel, but not before the GCC+Rust issues are all fixed. You shouldn't need non-GCC compilers to compile Linux and from what I can tell there isn't any GCC Rust compiler that's fully equivalent to the standard Rust compiler just yet.They say that Rust support is optional, but when the first big driver gets written in Rust it'll become mandatory. So either the Rust integration will fail and nothing important will get written in it, or it won't be optional. I'm not sure what comfort that's supposed to bring.
