LTP syscalls mount02 failed on mainline (Linux version 5.0.0) for all devices.

Results comparison link,
https://qa-reports.linaro.org/lkft/linux-mainline-oe/tests/ltp-syscalls-tests/mount02
you could see good and bad commit id in the above link.

Error log,
mount02 5 TFAIL : mount02.c:117: mount() was expected to fail with
EINVAL(22): TEST_ERRNO=ENOENT(2): No such file or directory

structure Inputs,
{&null, &mntpoint, &fs_type, 0, EINVAL, NULL, NULL},

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 ?
