Snippet  test code:
--------------------------
TEST(mount(*tc->device, *tc->mntpoint, *tc->fs_type, tc->flag, NULL));

if (TEST_RETURN != -1) {
tst_resm(TFAIL, "mount() succeded unexpectedly (ret=%li)",
         TEST_RETURN);
goto cleanup;
}

if (TEST_ERRNO != tc->exp_errno) {
tst_resm(TFAIL | TTERRNO,
         "mount() was expected to fail with %s(%i)",
         tst_strerrno(tc->exp_errno), tc->exp_errno);
goto cleanup;
}

do you notice this mount02 failure on mainline kernel ?
