zhangyi (F)	10ad750169	overlay: test whiteout check in impure dir ... The unmerged and impure upper directories may contain invalid whiteouts when we umount && modify lowerdir(e.g. clean up dir) and remount overlay. This may lead to whiteouts exposure and rmdir failure. This case test impure dir's whiteouts check in ovl_iterate() and ovl_remove_xxx().
