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.
