Linux Kernel Embraces Rust: Fewer Bugs, Higher Efficiency

Greg KH's email strongly advocates for incorporating Rust into the Linux kernel. His extensive experience resolving kernel bugs over 15+ years highlights Rust's ability to prevent common memory safety issues in C, such as memory overwrites, error path cleanups, and use-after-free errors. While C++ offers some improvements, Rust provides stronger memory safety guarantees. KH argues that using Rust for new drivers and kernel components will significantly reduce bugs, increase development efficiency, and free maintainers to focus on more complex logic issues and race conditions. Although maintaining mixed-language codebases is challenging, he believes the Linux community can overcome this hurdle, ensuring Linux's continued success for the next 20+ years.
