CONFIG_UNEVICTABLE_LRU: Add LRU list to track non-evictable pages

General informations

The Linux kernel configuration item CONFIG_UNEVICTABLE_LRU:

Help text

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.

See Documentation/vm/unevictable-lru.txt for more information.
