The migration\nscanner starts at the bottom of the zone and searches for all movable\npages within each area, isolating them onto a private list called\nmigratelist.  The free scanner starts at the top of the zone and searches\nfor suitable areas and consumes the free pages within making them\navailable for the migration scanner.

      "message": "ksm: memory hotremove migration only\n\nThe previous patch enables page migration of ksm pages, but that soon gets\ninto trouble: not surprising, since we\u0027re using the ksm page lock to lock\noperations on its stable_node, but page migration switches the page whose\nlock is to be used for that.  Another layer of locking would fix it, but\ndo we need that yet?\n\nDo we actually need page migration of ksm pages?  Yes, memory hotremove\nneeds to offline sections of memory: and since we stopped allocating ksm\npages with GFP_HIGHUSER, they will tend to be GFP_HIGHUSER_MOVABLE\ncandidates for migration.\n\nBut KSM is currently unconscious of NUMA issues, happily merging pages\nfrom different NUMA nodes: at present the rule must be, not to use\nMADV_MERGEABLE where you care about NUMA.  So no, NUMA page migration of\nksm pages does not make sense yet.\n\nSo, to complete support for ksm swapping we need to make hotremove safe.\nksm_memory_callback() take ksm_thread_mutex when MEM_GOING_OFFLINE and\nrelease it when MEM_OFFLINE or MEM_CANCEL_OFFLINE.  But if mapped pages\nare freed before migration reaches them, stable_nodes may be left still\npointing to struct pages which have been removed from the system: the\nstable_node needs to identify a page by pfn rather than page pointer, then\nit can safely prune them when MEM_OFFLINE.\n\nAnd make NUMA migration skip PageKsm pages where it skips PageReserved.\nBut it\u0027s only when we reach unmap_and_move() that the page lock is taken\nand we can be sure that raised pagecount has prevented a PageAnon from\nbeing upgraded: so add offlining arg to migrate_pages(), to migrate ksm\npage when offlining (has sufficient locking) but reject it otherwise.\n\nSigned-off-by: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nCc: Izik Eidus \u003cieidus@redhat.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Chris Wright \u003cchrisw@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Not only\ndoes it use up CPU time, but it also provokes lock contention and can\nleave large systems under memory presure in a catatonic state.\n\nThis patch series improves VM scalability by:\n\n1) putting filesystem backed, swap backed and unevictable pages\n   onto their own LRUs, so the system only scans the pages that it\n   can/should evict from memory\n\n2) switching to two handed clock replacement for the anonymous LRUs,\n   so the number of pages that need to be scanned when the system\n   starts swapping is bound to a reasonable number\n\n3) keeping unevictable pages off the LRU completely, so the\n   VM does not waste CPU time scanning them. ramfs, ramdisk,\n   SHM_LOCKED shared memory segments and mlock()ed VMA pages\n   are keept on the unevictable list.\n\nThis patch:\n\nisolate_lru_page logically belongs to be in vmscan.c than migrate.c.\n\nIt is tough, because we don\u0027t need that function without memory migration\nso there is a valid argument to have it in migrate.c.  However a\nsubsequent patch needs to make use of it in the core mm, so we can happily\nmove it to vmscan.c.\n\nAlso, make the function a little more generic by not requiring that it\nadds an isolated page to a given list.  Callers can do that.\n\n\tNote that we now have \u0027__isolate_lru_page()\u0027, that does\n\tsomething quite different, visible outside of vmscan.c\n\tfor use with memory controller.
