Safe self-referential data structures in Rust for the kernel

According to the machine-translated LWN feed coverage, self-referential data structures that can be used without unsafe code have long been a problem in Rust. They are often the most elegant algorithmic choice, yet under Rust's lifetime rules their implementation is practically impossible without unsafe. At Kangrejos 2026, Gary Guo presented a solution in the context of the kernel's pin_init crate, aimed at creating immovable structures, typically for interoperability with C.

The text states that the proposed changes could remove most lifetime-related unsafe code in the Nova driver and, eventually, in other Rust components. The item was published on October 16, 2026.
