It was in wrong place originally in ib_verbs.h because lately it returned all the entries from the cache.
So ib_cache.h was/is correct place.
But devel happened at pace where we eventually deprecated it.
So from pure compat perspective, yeah, it should be in wrong file i.e. ib_verbs.h but otherwise its correct in ib_cache.h.
