A detailed account of rewriting a Linux device driver from C to Rust, covering the challenges of kernel development including build configuration with Kconfig, managing complex Git workflows with multiple branches, creating safe Rust abstractions for C kernel APIs, and navigating the Linux kernel mailing list contribution process. The author demonstrates how reference counting solves borrow checker issues and shows practical examples of wrapping C structs, implementing iterators, and preventing buffer overflows in kernel code.
