└─>Add LRU list to track non-evictable pages
In linux kernel since version 2.6.28 (release Date: 2008-12-24)  
Keeps unevictable pages off of the active and inactive pageout
lists, so kswapd will not waste CPU time or have its balancing
algorithms thrown off by scanning these pages. Selecting this
will use one page flag and increase the code size a little,
say Y unless you know what you are doing.
