This is mentioned in the kernel doc ... "make htmldocs" at the
top level of the source tree. But probe() is a fine place to use
such synchronous function.
In general I'd be interested in seeing more of that info be part
of the standard kernel tree. Not that the "kerneldoc" is as
thorough as I'd like (compare to javadoc :) but everyone has
access, and it's more natural to maintain.
