It works everywhere, even in the docbook template, as long as you mark
it up correctly. Which in docbook means <function>func</function>.
That's because it's a post-proc path over the entire doc. But then the
entire point here is to move the overview sections all into kerneldoc,
so making the links in the templates more verbose shouldn't be a big
deal.
