That duplication is *precisely* the problem we have in Landlock. :)

(If you look at the patch series I've been sending with both the patches sent to
linux-security-modules@ and linux-man@, you'll see the duplication,
e.g. https://lore.kernel.org/all/20250226211814.31420-2-gnoack@google.com/)

Documentation of user space APIs is not unusual in the kernel documentation,
there is the entire subdirectory Documentation/userspace-api for it.
