If the end result is to do something like I proposed, then why take this intermediate step that just has to be backed out later? In other words, if our end goal is to have rdma_transport_is_ib() rdma_transport_is_iwarp() rdma_transport_is_roce() rdma_transport_is_opa() Then we should skip doing rdma_port_ll_is_*() as the answers to these items would be implied by rdma_transport_is_roce() and such. > Cc: Jason Gunthorpe > Cc: Doug Ledford > Cc: Ira Weiny > Cc: Sean Hefty > Signed-off-by: Michael Wang > --- > drivers/infiniband/core/agent.c | 2 +- > drivers/infiniband/core/cm.c | 2 +- > drivers/infiniband/core/cma.c | 27 ++++++++++++-------------= -- > drivers/infiniband/core/mad.c | 6 +++--- > drivers/infiniband/core/multicast.c | 11 ++++------- > drivers/infiniband/core/sa_query.c | 14 +++++++------- > drivers/infiniband/core/ucm.c | 3 +-- > drivers/infiniband/core/user_mad.c | 2 +- > drivers/infiniband/core/verbs.c | 5 ++--- > drivers/infiniband/hw/mlx4/ah.c | 2 +- > drivers/infiniband/hw/mlx4/cq.c | 4 +--- > drivers/infiniband/hw/mlx4/mad.c | 14 ++++---------- > drivers/infiniband/hw/mlx4/main.c | 8 +++----- > drivers/infiniband/hw/mlx4/mlx4_ib.h | 2 +- > drivers/infiniband/hw/mlx4/qp.c | 21 +++++++-------------- > drivers/infiniband/hw/mlx4/sysfs.c | 6 ++---- > drivers/infiniband/ulp/ipoib/ipoib_main.c | 6 +++--- > include/rdma/ib_verbs.h | 24 ++++++++++++++++++++++++ > net/sunrpc/xprtrdma/svc_rdma_recvfrom.c | 3 +-- > 19 files changed, 79 insertions(+), 83 deletions(-) >=20 > diff --git a/drivers/infiniband/core/agent.c b/drivers/infiniband/core/ag= ent.c > index f6d2961..27f1bec 100644 > --- a/drivers/infiniband/core/agent.c > +++ b/drivers/infiniband/core/agent.c > @@ -156,7 +156,7 @@ int ib_agent_port_open(struct ib_device *device, int = port_num) > goto error1;
