    RDMA/restrack: don't use uaccess_kernel() · 2f08ee36
    Steve Wise authored
    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.
    Fixes: 02d8883f ("RDMA/restrack: Add general infrastructure to track RDMA resources")
