This allows running different subsets of tests, e.g. $ ./tools/testing/kunit/kunit.py build $ ./tools/testing/kunit/kunit.py exec 'list*' $ ./tools/testing/kunit/kunit.py exec 'kunit*' This passes the "kunit_filter.glob" commandline option to the UML kernel, which currently only supports filtering by suite name.
