Re: [PATCH v8 3/3] selftests/mm: add new selftests for KSM

+/* Verify that KSM can be enabled / queried with prctl. */ +static void test_prctl(void) +{

• int ret;
• ksft_print_msg("[RUN] %s\n", __func__);
• ret = prctl(PR_SET_MEMORY_MERGE, 1, 0, 0, 0);
• if (ret < 0 && errno == EINVAL) {

• ksft_test_result_skip("PR_SET_MEMORY_MERGE not supported\n");
  

• return;
  

• } else if (ret) {

• ksft_test_result_fail("PR_SET_MEMORY_MERGE=1 failed\n");
  

• }

Just realized we're missing a "return;" in case of the failure here.
