[$] Safe self-referential data structures in kernel Rust
Self-referential structures that can be used without unsafe code have posed a problem for Rust for years. There are many cases where a self-referential data structure is the elegant algorithmic choice, but implementing it in accordance with Rust's lifetime rules is all but impossible. At Kangrejos 2026, Gary Guo presented a clever solution to the problem in the context of the kernel's pin_init…
