I was assuming that the kernel side would never do that.

There's some kind of "catch_unwind()" thing that catches a Rust
"panic!" thing, but I think it's basically useless for the kernel.

Typical Rust error handling should match the regular kernel
IS_ERR/ERR_PTR/PTR_ERR model fairly well, although the syntax is
fairly different (and it's not limited to pointers).
