Rust in Linux: Maturing with Support from Cisco, Samsung, Canonical

ZDNet shares on update on "Rust in Linux: Where we are and where we're going next," citing a talk at the Linux Plumbers Conference in Richmond, Virginia by Linux/Rust developer Miguel Ojeda:In brief, Rust Linux is continuing to mature and is getting strong support from developers and vendors, such as Cisco, Samsung, and Canonical... Rust is taking the steps it needs to become - along with C - a fully-fledged member of the Linux language toolchain... That's not to say that we're ready to retire C for Rust just yet. In fact, that day is unlikely ever to come. But Rust is definitely on its way to becoming an important language for Linux development... As for the day-to-day work that's required to make Rust fully integrated with Linux, the "official" website of the initiative is now the self-explanatory Rust for Linux. This site is your one-stop source for all things Rust on Linux... However, the move forward has not been straightforward. Rust on Linux developers have discovered some problems along the way. For example, while deadlocks, when two or more threads are waiting on the other to finish, are safe in Rust, because they don't result in undefined behavior, they're not safe in the Linux kernel. The programmers are working on fixing this issue... A related issue is that there's growing interest in backporting Rust support into long-term support (LTS) versions of Linux, specifically 5.15 and 6.1. Some people are especially showing interest in the super LTS Linux 6.1 kernel. However, Linux doesn't generally allow backports into LTS Linuxes. So, if you really, really want fully featured Rust support in an older LTS kernel, you're going to need to pay for it in one way or the other. Another general rule that Rust developers have decided they're going to try to "break" is the rule against duplicate drivers. Usually, no one wants anyone wasting time reinventing the wheel, but some maintainers are open to the idea of experimenting with Rust, by starting simple with a driver they're already familiar with... These movements are small steps forward, but they're all critical for making Rust equal to C as a Linux programming language.
