I added my "Acked-by:" for the __WARN to WARN_ON part. In addition, the rest
looks good.

I do not need a Reported-by to be added. I'm a volunteer, thus it does not
matter how many times my name is mentioned. Another one will never increase my
remuneration.

I have also submitted a patch to make certain that __WARN is defined even when
CONFIG_DEBUG is not defined. It may not be accepted, but if it does, no one else
will be caught this way.
