parentRDMA/verbs: Check existence of function prior to accessing it (diff)
RDMA/restrack: don't use uaccess_kernel()
uaccess_kernel() isn't sufficient to determine if an rdma resource is user-mode or not. For example, resources allocated in the add_one() function of an ib_client get falsely labeled as user mode, when they are kernel mode allocations. EG: mad qps. The result is that these qps are skipped over during a nldev query because of an erroneous namespace mismatch. So now we determine if the resource is user-mode by looking at the object struct's uobject or similar pointer to know if it was allocated for user mode applications.
