Changes since RFC v2: - Change fake suite and test case names. - Add a few ASSERT statements. Changes since RFC v1: - This is a new patch. lib/kunit/executor_test.c | 116 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 116 insertions(+) diff --git a/lib/kunit/executor_test.c b/lib/kunit/executor_test.c index d7ab069324b5..01280cb8d451 100644 --- a/lib/kunit/executor_test.c +++ b/lib/kunit/executor_test.c @@ -7,6 +7,7 @@ */ #include +#include static void kfree_at_end(struct kunit *test, const void *to_free);
