I also like to include a Context: section which lists whether the function takes locks / requires locks to be held / can be called in hard or soft interrupt context / may sleep / requires refcounts be held / ... Generally, what do you expect from your callers, and what your callers can expect from you. I don't understand the thing you're documenting, so it may not make sense to talk about interrupt context, for example.
