I think, existing following code will take care of this. Are you
seeing the sanitizer issue if the change is only updating
rte_graph_cluster_stats alignment?
/* For a given cluster, max nodes will be the max number of graphs */
cluster_node_size += cluster->nb_graphs * sizeof(struct rte_node *);
cluster_node_size = RTE_ALIGN(cluster_node_size, RTE_CACHE_LINE_SIZE);
