Since you have it in a C header and in `bindings_helper.h`, then you
should be able to use `#[export]`, which will do a typecheck that the
signatures match (it also does the `no_mangle`, so you can replace
it):

Please use the "kernel vertical style" for imports (it is done
automatically by `rustfmt` too by adding the `//`):

  https://docs.kernel.org/rust/coding-guidelines.html#imports

We have `size_of`, `align_of` and so on in the prelude, so you can use
those directly:

I hope that helps!
