13 This document describes the Linux memory manager's "Unevictable LRU"
26 The Unevictable LRU
29 The Unevictable LRU facility adds an additional LRU list to track unevictable
38 will spend a lot of time scanning the LRU lists looking for the small fraction
58 The Unevictable LRU infrastructure consists of an additional, per-node, LRU list
63 PG_active flag in that it indicates on which LRU list a page resides when
66 The Unevictable LRU infrastructure maintains unevictable pages on an additional
67 LRU list for a few reasons:

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
208 4. non-LRU movable page flags
210 There are two page flags for supporting non-LRU movable page.
230 For testing of non-LRU movable pages, VM supports __PageMovable() function.

| D | memory.rst | 47 - pages are linked to per-memcg LRU exclusively, and there is no global LRU.
185 updated. page_cgroup has its own LRU on cgroup.
192 Some pages which are never reclaimable and will not be on the LRU
212 Note: we just account pages-on-LRU because our purpose is to control amount
213 of used pages; not-on-LRU pages tend to be out-of-control from VM view.
249 The global LRU(kswapd) can swap out arbitrary pages. Swap-out means
