Miguel Ojeda sent out his pull request of the new Rust kernel code slated for introduction in Linux 7.4. It's a big one this round due to updating the Zerocopy vendored library plus updating other Rust crates for the kernel.
The Zerocopy crate update is a big one in jumping eight versions ahead. This is the code providing traits and macros to safely convert between raw byte sequences and structured types. Rust for Linux 7.4 also has other toolchain and infrastructure updates, enabling the unstable proc_macro_span feature for better diagnostics of all procedural macros, and more.
The Rust kernel create adds new "mem" and "ratelimit" modules while improving some of the existing modules. The pin-init crate is adding support for tuple structs as well as allowing for the safe creation of self-references. There is also much improved diagnostics.
More details on these central Rust code changes for Linux 7.4 can be found via this pull request. Via individual subsystem pull requests will also be more Rust code for Linux 7.4, like the NVIDIA Nova driver improvements for Linux 7.4 and the other Rust DRM infrastructure work that brings.
How much of this will be slop?
Everything you understand about it is currently slop, that's not ai's fault, it's yours
