Thanks for your comment. Could you please explain it a bit more to me?

I am new to the kernel sphinx documentation so I looked it up in
Documentation/doc-guide/sphinx.rst 'Cross-referencing'. It is listed as
the preferred way to reference other documents if I understand it
correctly.

Should the doc-guide be updated then if a rst reference is preferred?

Best,
Markus
