+        help
+          Add swap management feature to memory resource controller. When you
+          enable this, you can limit mem+swap usage per cgroup. In other words,
+          when you disable this, memory resource controller has no cares to
+          usage of swap...a process can exhaust all of the swap. This extension
+          is useful when you want to avoid exhaustion swap but this itself
+          adds more overheads and consumes memory for remembering information.
+          Especially if you use 32bit system or small memory system, please
+          be careful about enabling this. When memory resource controller
+          is disabled by boot option, this will be automatically disabled and
+          there will be no overhead from this. Even when you set this config=y,
+          if boot option "noswapaccount" is set, swap will not be accounted.
