Block Layer Rust API for Linux Kernel Device Drivers

Explore the integration of Rust as a second programming language in the Linux Kernel through this 25-minute conference talk from the Linux Plumbers Conference. Delve into the progress of the Rust for Linux project in developing a general framework for writing Linux kernel device drivers in safe Rust, with a focus on the block layer's missing components. Examine the work done to enable Rust drivers in the block layer, showcased through two examples: the Rust null_blk driver and the Rust NVMe driver. Analyze performance results and discuss optimization challenges encountered during development. Gain insights into the hurdles faced while attempting to upstream the Rust block layer API and consider potential paths forward for the project.
