RE: [PATCH 2/2] netprio_cgroup: Optimize the priomap copy loop slightly

From: David Laight <hidden>
Date: 2012-09-11 11:48:39
Also in: lkml

-	for (i = 0;
-	     old_priomap && (i < old_priomap->priomap_len);
-	     i++)
-		new_priomap->priomap[i] = old_priomap->priomap[i];
+	if (old_priomap) {
+		old_len = old_priomap->priomap_len;
+
+		for (i = 0; i < old_len; i++)
+			new_priomap->priomap[i] = old_priomap->priomap[i];
+	}
Or:
	memcpy(new_priomap->priomap, old_priomap->priomap,
		old_priomap->priomap_len * sizeof old_priomap->priomap[0]);
