201 * Lower hardlinks may be broken on copy up to different in ovl_getattr()
202 * upper files, so we cannot use the lower origin st_ino in ovl_getattr()
206 * same dir on a lower layer. With the "verify_lower" in ovl_getattr()
207 * feature, we do not use the lower origin st_ino, if in ovl_getattr()
