I don't understand what's going on here.  Apparently there's something
special about two colons?  I saw plenty of double colons in
Documentation/, but I couldn't quickly find out what it means.

If kernel-doc thinks "example:" is a mistake, maybe we could recast
the sentence as "Example usage:"?  Putting a double colon here makes
the text look like a mistake to this human reader.
