samples: rust_misc_device: fix markup in top-level docs The meaning of /// is to document the thing that comes after it, so currently the example is documentation for the `use core::pin::Pin;` statement. To write top-level docs (and have them rendered as such in the html by rustdoc), use //! instead. This does not change the contents of the docs at all. The only change is changing /// to //!.

rust: module: introduce `authors` key In the `module!` macro, the `author` field is currently of type `String`. Since modules can have multiple authors, this limitation prevents specifying more than one. Add an `authors` field as `Option<Vec<String>>` to allow creating modules with multiple authors, and change the documentation and all current users to use it. Eventually, the single `author` field may be removed. [ The `modinfo` key needs to still be `author`; otherwise, tooling may not work properly, e.g.: $ modinfo --author samples/rust/rust_print.ko Rust for Linux Contributors I have also kept the original `author` field (undocumented), so that we can drop it more easily in a kernel cycle or two. - Miguel ] Suggested-by: Miguel Ojeda <ojeda@kernel.org> Link: https://github.com/Rust-for-Linux/linux/issues/244 Reviewed-by: Charalampos Mitrodimas <charmitro@posteo.net> Reviewed-by: Alice Ryhl <aliceryhl@google.com> Reviewed-by: Andreas Hindborg <a.hindborg@kernel.org> Signed-off-by: Guilherme Giacomo Simoes <trintaeoitogc@gmail.com> Link: https://lore.kernel.org/r/20250309175712.845622-2-trintaeoitogc@gmail.com [ Fixed `modinfo` key.
