Rusty Swapping: Rewriting a Zswap Backend in Rust

Explore the process of rewriting a zswap backend in Rust for the Linux kernel in this 39-minute conference talk. Delve into the growing popularity of Rust as a second high-level language for kernel development and its potential applications in various subsystems. Learn about the zblock backend for zswap and understand the motivations behind reimplementing it in Rust. Discover the main principles of zblock that remain consistent across different programming languages. Gain insights into the challenges encountered during the Rust implementation and compare the performance and complexity of both versions. Evaluate the pros and cons of each approach to determine which implementation is most suitable for submission to the mainline kernel.
