Please, do not make indentation-only changes, specially as part of a larger
change. It makes the patch much harder to review.

These KUNIT_ macros are way less readable than the existing code,
IMO. the old macro makes it obvious what we are checking, without having
to dig into the definition. But, meh, I can live with it.

Yuck. This is even less readable. Is there a kunit macro that receives
an expression, similar to WARN_ON/BUG_ON? It would be way more readable.
Something like this.
KUNIT_BLA(test, utf8_strncmp(um, &s1,&s2) == 0, "BAD TEST!")
