Rust in the Linux kernel
summary
A Rust kernel module that creates a /dev char device animation is implemented and successfully inserts and logs major/minor numbers; build uses Kbuild plus Rust static libraries unarchived and linked with ld, and relies on xargo nightly to compile libcore for the kernel target. C ABI work includes marking entry points no_mangle and extern "C" functions, using DIY bindings or small C wrappers for preprocessor-heavy APIs, and a safe mutex wrapper that maps to kernel mutexes; overall runtime works and required far less unsafe code than expected.
