Please don't add "Signed-off-by" tags for other people. That tag should
only come from people with actual authorship on the patch.

Instead, in this case,

Suggested-by: Laszlo Ersek <lersek@redhat.com>

would be appropriate (and welcome too :) ).

I'll check this patch in more detail later.

Thanks,
Laszlo
