In which case?  ext2_delete_entry() failing?

-       ext2_delete_entry(old_de, old_page, old_page_addr);
+       err = ext2_delete_entry(old_de, old_page, old_page_addr);
+       if (err)
+               goto out_dir;

and on out_dir: we have
out_dir:
        if (dir_de)
                ext2_put_page(dir_page, dir_page_addr);
out_old:
        ext2_put_page(old_page, old_page_addr);
out:
        return err;

How is the old_page leaked here?
