Note that this submission is about a learning project where someone aims to write a (minimal?) Linux ABI compatible kernel. To directly answer your question though. It's not that 'Rust memory allocations' panic. Rather it was the case that allocations widely used when the initiative was started could panic. This is being solved by writing a library with non-panicking memory allocations to be used in kernel development [1]. However, I'm not involved with this in any way, so I may be wrong. 1. https://rust-for-linux.github.io/docs/alloc/ https://rust-for-linux.github.io/docs/alloc/
