I think backwards compatibility and simplicity count for something. The
only point about libibverbs is that the group rdma permissions are
already applied to /dev/infiniband/uverbsX, and the class of
users/applications that use those nodes are the same as the ones that
would use /dev/infiniband/rdma_cm. So given that any systems where
libibverbs is in use have already configured the rdma group, it seems we
should at least consider whether we want to break that setup and/or
introduce a different mechanism to do the same thing.

I think I've gotten that message. But could you give a hint as to what
alternative mechanism you are using? It's very frustrating to get
replies to all my comments except for when I ask what you want me to do.
