Linus Torvalds has taken the initial Rust codemergeinto the Linux kernel mainline.

Yesterday, the initial Rust infrastructure code was merged into the mainline Git code tree in the Linux 6.1 kernel. Linus had expressed such plans at the Kernel Summit a few weeks ago, and it was widely expected to happen, but as recently as this weekend, there were still some Linux users who disagreed with the idea of ​​the Rust programming language supporting the Linux kernel. But now it has landed.

The initial 12.5k lines of new code provide only the low-level infrastructure and some very basic integrations, and future PRs are said to add more subsystem abstractions, multiple Rust-written drivers, and more. Currently, building a Linux kernel with Rust support is still optional.
