Looking further, in the same function I also don't see any other uses of
the tested field in:

                if (req->rq_oi.oi_md)
                        OBD_FREE_LARGE(req->rq_oi.oi_md, req->rq_buflen);

        if (set->set_lockh)
		lov_llh_put(set->set_lockh);

Can these be dropped as well?

thanks,
julia
