The HIP09 supports XRC transport service, it greatly saves the number of QPs required to connect all processes in a large cluster. This series first adds support of ibv_create_qp/srq_ex which are necessary interfaces for XRC, fixes an issue about CQ locks that is also required, then XRC is fully supported at last.
