This is https://github.com/Rust-for-Linux/linux/pull/883, also handled
by Vinay's patch
https://lore.kernel.org/rust-for-linux/20230118160220.776302-1-varmavinaym@gmail.com/.

Lina's approach is arguably a bit more idiomatic in Python in that it
is usually encouraged to follow the "Easier to ask for forgiveness
than permission" approach.

Lina, would you like to submit yours? Or do you prefer a `Link: ` /
`Reported-by: ` / `Co-developed-by: ` here?

By the way, note that in the kernel crate we are avoiding `mod.rs`
files, instead using `name.rs` in the parent folder, in other to make
it easier to find the files. I will add a note about it in the docs.

Cheers,
Miguel
