Rust for Linux
summary
Rust support is now merged (initial in v6.1) and the project reports active growth — ~500 mailing-list subscribers, ~70 regular chat users and ~8,000 messages last year — while industry sponsors (ISRG, Cisco, Collabora) back work on real subsystems like Binder, VFS, mvme and drivers. Concrete outputs include Arc, Mutex, SpinLock zero-cost Rust wrappers for kernel primitives, a pinned-init API that solves safe pinned initialization, KUnit doctest integration, klint static checks that track preemption to validate locking rules, and a GCC-based backend that can build Rust kernel modules without source changes. Ongoing: mitigations, CFI support, branch/workflow policies and Rust-version tracking.
