The "rnull" Block Driver Developed in Rust

The "rnull" block driver in Rust provides a new benchmark for block-layer implementations, matching its C counterpart.

The "rnull" block driver demonstrates the feasibility of writing a simple block driver using Rust APIs. Developed by Andreas Hindborg, this driver achieves feature parity with its C counterpart, allowing for comparisons between block-layer implementations. It serves as an important example of configurability and registration as a block device provider.
