-		  Add swap management feature to memory resource controller. When you

-		  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 "swapaccount=0" is set, swap will not be accounted.
-		  Now, memory usage of swap_cgroup is 2 bytes per entry. If swap page
