I have two nitpicks, fill free to ignore.
When test is run with -vvv, verifier log says:
-- BEGIN PROG LOAD LOG --
func#0 @0
Cannot replace static functions
processed 0 insns ...
-- END PROG LOAD LOG --
Would it be possible to match the error message in this test?
Also, maybe kernel should be tweaked to be a bit more informative,
as message about static function is confusing, wdyt?
