Explore advanced Rust programming techniques for kernel development in this 19-minute conference talk from the Linux Plumbers Conference. Delve into the challenges of implementing external locking mechanisms for internally synchronized C kernel data structures when exposed to Rust code, particularly focusing on structures like XArray that require internal synchronization. Learn how traditional C approaches to temporarily unlocking during memory allocation create unique problems in Rust due to mutable borrowing constraints through lock guards. Discover the innovative Rust API solution presented at Kangrejos that enables external lock usage while maintaining the ability to momentarily drop locks for memory allocation purposes. Examine how this approach addresses race condition handling during lock drops and its impact on data structures implementing the Entry pattern. Review benchmark results from actual kernel code implementations rather than theoretical examples, and participate in community discussions aimed at refining the external locking API before patches are submitted for review.
