2023-12-21rust: support `srctree`-relative linksMiguel Ojeda1-1/+1
Some of our links use relative paths in order to point to files in the source tree, e.g.: //! C header: [`include/linux/printk.h`](../../../../include/linux/printk.h) /// [`struct mutex`]: ../../../../include/linux/mutex.h These are problematic because they are hard to maintain and do not support `O=` builds. Instead, provide support for `srctree`-relative links, e.g.: //! C header: [`include/linux/printk.h`](srctree/include/linux/printk.h) /// [`struct mutex`]: srctree/include/linux/mutex.h The links are fixed after `rustdoc` generation to be based on the absolute path to the source tree. Essentially, this is the automatic version of Tomonori's fix [1], suggested by Gary [2].

2023-07-19rust: sync: make doctests compilable/testableMiguel Ojeda1-0/+1
Rust documentation tests are going to be build/run-tested with the KUnit integration added in a future patch, thus update them to make them compilable/testable so that we may start enforcing it.

2023-04-22rust: lock: introduce `Mutex`Wedson Almeida Filho1-0/+118
This is the `struct mutex` lock backend and allows Rust code to use the kernel mutex idiomatically.
