ib_sa_service_rec_query() was introduced in kernel v2.6.13 by commit
cbae32c56314 ("[PATCH] IB: Add Service Record support to SA client")
in 2005. It was not used then and have never been used since.

You shouldn't stop there and remove ib_sa_service_rec_callback,
ib_sa_service_rec_release, ib_sa_service_query and probably
ib_sa_service_rec.
Thanks

I checked all functions called from ib_sa_service_rec_query() were used elsewhere, and they were indeed. But overlooked the function assignments :-) Thanks for pointing it out. A v2 will follow.
