The code to skip filesystems in the case of all filesystems is in the
run_tcase_per_fs() function:

static int run_tcases_per_fs(void)
{
        int ret = 0;
        unsigned int i;
        const char *const *filesystems = tst_get_supported_fs_types(tst_test->skip_filesystems);

The skip_filesystems array is passed to the tst_get_supporte_fs_types()
function which filters out them.
