I think this could be merged with patch 5, as it's not useful on its
own. Also, a few of the symbol names might be a little too generic to
be exported: maybe we should give them a 'kunit_assert' prefix?

Cheers,

I'm a bit worried about having such a generic name exported, even
conditionally and to a namespace. Maybe we could give this a
'kunit_assert' prefix, or put it in a separate, more specific
namespace?
