What is the rationale for adding those tests unconditionally whenever
CONFIG_KUNIT_TEST is enabled ? This completely messes up my test system
because it concludes that it is pointless to continue testing
after the "Unable to handle kernel NULL pointer dereference" backtrace.
At the same time, it is all or nothing, meaning I can not disable
it but still run other kunit tests.
