Hi Markus,

   I think you linked this to me yesterday that it should be described
imperatively:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?h=v6.5-rc3#n155

I don’t follow the purpose of this reference. This points to user impact
but this is a selftest, so I don’t see any user impact here. Or is there
anything I missed?

I am not following this question . Can you be more specific or provide an
example?
