Memory safety may land in C++ in the near future (see also
https://herbsutter.com/2024/03/). If memory-safe C++ or memory-safe C
would be adopted in the kernel, it would allow writing memory-safe
drivers without having to add complicated bindings between existing C
code and new Rust code. Please do not take this as personal criticism -
I appreciate the effort that has been spent on coming up with great
Rust bindings for the Linux kernel block layer.

Thanks,

Bart.
