Agreed Stephen, will switch to rte_calloc in patch v2:

-	pp->kickfds = rte_malloc("virtio_user_proc_priv",
-				 total_queues * sizeof(int), 0);
-	pp->callfds = rte_malloc("virtio_user_proc_priv",
-				 total_queues * sizeof(int), 0);
+	pp->kickfds = rte_calloc("virtio_user_proc_priv",
+				 total_queues, sizeof(int), 0);
+	pp->callfds = rte_calloc("virtio_user_proc_priv",
+				 total_queues, sizeof(int), 0);
