The kunit_test_init_section_suites() registered tests aren't in the .init section as debugfs entries are retained for results reporting (without an ability to rerun them). IIUC, the __kunit_init_test_suites->CONCATENATE(..., _probe) suffix is intended to suppress the modpost warning - @kunit-dev: any ideas why this isn't working as intended? Thanks, David
