Most of the resources the RDMA cgroup handles are only allocated at
the beginning of the application. The RDMA subsystem allows direct
user-space access to the devices, so most of the hot path operations
don't go through the kernel at all.
It is true though that for some applications MR registration and
de-registration is in the hot path.
