If it's is 'y', then don't even make it an option at all, just always have it :) 'y' is almost always reserved for "your machine will not function properly without this enabled". > - CONFIG_KUNIT_TEST, CONFIG_KUNIT_EXAMPLE_TEST should be default n So no need to specify anything, 'n' is the default. thanks, greg k-h
