In 2022 we will very likely see the experimental Rust programming language support within the Linux kernel mainlined. Sent out this morning were the updated patches introducing the initial support and infrastructure around handling of Rust within the kernel.
This summer saw the earlier patch series posted for review and discussion around introducing Rust programming language support in the Linux kernel to complement its longstanding C focus. In the months since there has been more progress on enabling Rust for the Linux kernel development, Linus Torvalds is not opposed to it, and others getting onboard with the effort. Rust for the Linux kernel remains of increasing interest to developers over security concerns with Rust affording more memory safety protections, potentially lowering the barrier to contributing to the kernel, and other related benefits.
A few minutes ago Miguel Ojeda sent out the "v2" patches for Rust support in the kernel. With these updated packages, the Rust code is now relying on stable Rust releases rather than the beta compiler state previously, new modularization options added, stricter code enforcements, extra Rust compiler diagnostics enabled, new abstractions for in-kernel use, and other low-level code improvements.
Red Hat is also now joining Arm, Google, and Microsoft in voicing their support for Rust code within the Linux kernel.
The new patch series can be found on the LKML for review and discussion. We'll see how this revision is taken by other upstream developers and with some luck in the coming months we will see this preliminary support mainlined. As with most kernel additions, the support is configurable at build-time if still wanting to compile a future Linux kernel build without this complementary Rust support.
