The amount of unsafe is pretty small and limited to where the interfacing with io or relevant stuff is actually happening. For example (random selection) https://lkml.org/lkml/2023/3/7/764 has a few unsafes, but either: a) trivial structure access, or b) documented regarding why it's valid. The rest of the code still benefits.

But that's not the only reason Rust is useful - see the end of the write-up from the module author https://asahilinux.org/2022/11/tales-of-the-m1-gpu/ ("Rust is magical!" section)
