[GIT PULL] Landlock updates for v6.9

[Mickaël Salaün]

Hi Linus,

This PR brings some miscellaneous improvements, including new KUnit tests,
extended documentation and boot help, and some cosmetic cleanups.

Additional test changes already went through the net tree.

Please pull these changes for v6.9-rc1.  This commit merged cleanly with
your master branch.  The kernel code has been tested in the latest
linux-next releases for a few weeks.

Regards,
 Mickaël
