26 The Unevictable LRU
29 The Unevictable LRU facility adds an additional LRU list to track unevictable
58 The Unevictable LRU infrastructure consists of an additional, per-node, LRU list

152 Non-LRU page migration
159 *LRU* pages. However, there are potential non-LRU pages which can be migrated
167 To overcome the problem, VM supports non-LRU page migration which provides
168 generic functions for non-LRU movable pages without driver specific hooks
