Yeah, this is not the first time such a question has been raised ;) In fact,
some people (see, e.g., Peter's comment in this thread) have also suggested
extending it to {mutex,rwsem,bit_spin}_is_locked  (the number of uses would
then increase to a few hundreds, and lockdep would need some extensions...).
Of course, removing the docbook headers should not cause particular trouble,
once/if the removal of these primitives will be realized... ;)
