implementation of get_mr that I could locate is rds_ib_get_mr()\n which can return an ERR_PTR if the conn (4th) argument is NULL.\n\n* ret is set to PTR_ERR(trans_private).\n rds_ib_get_mr can return ERR_PTR(-ENODEV) if the conn (4th) argument is NULL.\n Thus ret may be -ENODEV in which case the code in question will execute.\n\nConclusion:\n* cp may be NULL at the point where this patch adds a
