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. |
