Miguel Ojeda has already submitted the core Rust programming language infrastructure updates intended for the Linux 6.19 merge window. In the pull request he also notes that moving forward the minimum supported Rust version for compiling the Linux kernel will likely follow whatever the minimum Rust version currently in use by the latest Debian stable release.
The Rust for Linux 6.19 updates include adding support for Syn as a parsing library for parsing strams of Rust tokens into a syntax tree of Rust source code.
Rust in this next version of the Linux kernel also continues enhancing its “kernel” crate with support for more features, support for C string literals in Rust 1.77+, and documentation updates.
As part of the documentation updates it’s noted in the pull request:
“We are planning to propose that the minimum supported Rust version in Linux follows Debian Stable releases, with Debian 13 being the first one we upgrade to, i.e. Rust 1.85.”
This pull request also drops no longer active Rust co-maintainer Alex Gaynor from being one of the listed maintainers.
See this pull request for the main set of Rust updates for Linux 6.19. This is just the core Rust infrastructure work with other Linux 6.19 pull requests expected to bring other new Rust code like continued work on Rust DRM kernel graphics drivers and Rust I2C driver support.
