By the way, we are trying to write examples close to normal kernel
code as possible, so could you please use `?` here instead of
`unwrap()`?

It is not a big deal, when within `assert`s, but there is value in not
showing any `unwrap()`s, and to spot easily places where we actually
do `unwrap()`.

Also, please use intra-doc links wherever they may work, e.g. I think
[`PowerOfTwo`] and [`None`] will work.

Thanks!

Cheers,
Miguel
