It’s a bit clickbait-y, but the article is short, to the point, and frankly satisfying. If there is such a thing as good clickbait, then this might be it. Impressive work!
The topic of the Rust experiment was just discussed at the annual Maintainers Summit. The consensus among the assembled developers is that Rust in the kernel is no longer experimental — it is now a core part of the kernel and is here to stay. So the "experimental" tag will be coming off. Congratulations are in order for all of the Rust-for-Linux team.
