Not only does this fail, it spits a WARN_ON_ONCE() in dmesg. Which in
turn gets flagged as a failure in the test in our CI.

What's the policy with kunit tests causing warnings? I think it's
reasonable for any CI to flag dmesg warnings. We shouldn't be hitting
those. Filtering the warnigs is a tricky business.

BR,
Jani.
