Oh, sure, things like the protocol string table are just stupid and it's great that you caught it. I just don't think it makes sense to scrutinize bss __initdata. It's not in kernel image and goes away once the kernel boots. It's okay to a bit liberal with them for the sake of simplicity. Thanks. -- tejun
