ib_device_register_rdmacg, ib_device_unregister_rdmacg are the only
two functions called from IB/core as its tied to functionality.
They can also be implemented as NULL call when CONFIG_CGROUP_RDMA is undefined.
(Similar to ib_rdmacg_try_charge and others).
I didn't do because occurrence of call of register and unregister is
limited to single file and only twice compare to charge/uncharge
functions.
Either way is fine with me, I can make the changes which you
described. Let me know.
