unaccount_page_cache_page
lru_cache_add_active_or_unevictable	lru_cache_add_active_or_unevictable@page: the page to be added to LRU@vma: vma in which page is mapped for determining reclaimability* Place @page on the active or unevictable LRU list, depending on its* evictability
lru_deactivate_fn
lru_lazyfree_fn
move_pages_to_lru	This moves pages from @list to corresponding LRU list.* We move them the other way if the page is referenced by one or more* processes, from rmap.* If the pages are mostly unmapped, the processing is fast and it is
shrink_active_list
check_and_migrate_cma_pages
clear_page_mlock	LRU accounting for clear_page_mlock()
mlock_vma_page	Mark page as mlocked if not already.* If page on LRU, isolate and putback to move to unevictable list.
munlock_vma_page	munlock_vma_page - munlock a vma page@page: page to be unlocked, either a normal page or THP page head returns the size of the page as a page mask (0 for normal page,* HPAGE_PMD_NR - 1 for THP head page)
pfn_in_hpage
page_vma_mapped_walk	page_vma_mapped_walk - check if @pvmw->page is mapped in @pvmw->vma at@pvmw->address@pvmw: pointer to struct page_vma_mapped_walk. page, vma, address and flags* must be set. pmd, pte and ptl must be NULL.* Returns true if the page is mapped in the vma
page_mapped_in_vma	page_mapped_in_vma - check whether a page is really mapped in a VMA@page: the page to test@vma: the VMA to test* Returns 1 if the page is mapped into the page tables of the VMA, 0* if the page is not mapped into the page tables of this VMA. Only
do_page_add_anon_rmap	Special version of the above for do_swap_page, which often runs* into pages that are exclusively owned by the current process.* Everybody else should continue to use page_add_anon_rmap above.
page_add_new_anon_rmap	page_add_new_anon_rmap - add pte mapping to a new anonymous page@page: the page to add the mapping to@vma: the vm area in which the mapping is added@address: the user virtual address mapped@compound: charge the page as compound or small page
rmap_walk_anon	map_walk_anon - do something to anonymous page using the object-based* rmap method@page: the page to be handled@rwc: control variable according to each walk type* Find all the mappings of a page using the mapping pointer and the vma chains
rmap_walk_file	map_walk_file - do something to file page using the object-based rmap method@page: the page to be handled@rwc: control variable according to each walk type* Find all the mappings of a page using the mapping pointer and the vma chains
get_swap_bio
count_swpout_vm_event
__delete_from_swap_cache	This must be called only on pages that have* been verified to be in the swap cache.
delete_from_swap_cache	This must be called only on pages that have* been verified to be in the swap cache and locked.* It will never put the page into the free list,* the caller has a reference on the page.
put_swap_page	Called after dropping swapcache to decrease refcnt to swap entries.
migrate_page_add
putback_movable_pages	Put previously isolated pages back onto the appropriate lists* from where they were once taken off for compaction/migration.* This function shall be used whenever the isolated pageset has been* built from lru, balloon, hugetlbfs page
expected_page_refs
migrate_page_move_mapping	Replace the page in the mapping.* The number of remaining references must be:* 1 for anonymous pages without a mapping* 2 for pages with a mapping* 3 for pages with a mapping and PagePrivate/PagePrivate2 set.
copy_huge_page
unmap_and_move	Obtain the lock on page, remove all ptes and migrate the page* to the newly allocated page in newpage.
add_page_for_migration	Resolves the given address to a struct page, isolates it from the LRU and* puts it to the given pagelist
mem_cgroup_move_account	mem_cgroup_move_account - move account of the page@page: the page@compound: charge the page as compound or small page@from: mem_cgroup which the page is moved from.@to: mem_cgroup which the page is moved to. @from != @to.
mem_cgroup_try_charge	mem_cgroup_try_charge - try charging a page@page: page to charge@mm: mm context of the victim@gfp_mask: reclaim mode@memcgp: charged memcg return@compound: charge the page as compound or small page Try to charge @page to the memcg that @mm belongs
mem_cgroup_commit_charge	mem_cgroup_commit_charge - commit a page charge@page: page to charge@memcg: memcg to charge the page to@lrucare: page might be on LRU already@compound: charge the page as compound or small page* Finalize a charge transaction started by
mem_cgroup_cancel_charge	mem_cgroup_cancel_charge - cancel a page charge@page: page to charge@memcg: memcg to charge the page to@compound: charge the page as compound or small page Cancel a charge transaction started by mem_cgroup_try_charge().
mem_cgroup_migrate	mem_cgroup_migrate - charge a page's replacement@oldpage: currently circulating page@newpage: replacement page* Charge @newpage as a replacement page for @oldpage. @oldpage will* be uncharged upon free.
mem_cgroup_swapout	mem_cgroup_swapout - transfer a memsw charge to swap@page: page whose memsw charge to transfer@entry: swap entry to move the charge to* Transfer the memsw charge of @page to @entry.
mem_cgroup_try_charge_swap	mem_cgroup_try_charge_swap - try charging swap space for a page@page: page being added to swap@entry: swap entry to charge* Try to charge @page's memcg for the swap space at @entry.* Returns 0 on success, -ENOMEM on failure.
mlock_migrate_page	mlock_migrate_page - called only from migrate_misplaced_transhuge_page()* (because that does not go through the full procedure of migration ptes):* to migrate the Mlocked page flag; update statistics.
