/proc/ioports overrun patch

[Marcelo Tosatti]

Hello Olof,

Let me make sure I understood the patch right:

Your change to do_resource_list() will avoid copying out of bound by
truncating the resource output. Which means users might get truncated
information (only information that fits in the buffer) and not the full
information.

Is that correct?

If so, I would prefer to have a fix which outputs the full resource
information. For that we would need seq_file().

Please correct me if my reading of the code is wrong.

Thanks
