Asterinas: a new Linux-compatible kernel project

Asterinas is a new Linux-ABI-compatible kernel project written in Rust, based on what the authors call a “framekernel architecture”. The project overlaps somewhat with the goals of the Rust for Linux project, but approaches the problem space from a different direction by trying to get the best from both monolithic and microkernel designs.
