Type	Parameter	Name
const struct page *	page

**Caller**
Name	Describe
get_futex_key	get_futex_key() - Get parameters which are the keys for a futex@uaddr: virtual address of the futex@fshared: 0 for a PROCESS_PRIVATE futex, 1 for PROCESS_SHARED*@key: address where result is stored
lru_lazyfree_fn
mark_page_lazyfree	mark_page_lazyfree - make an anon page lazyfree@page: page to deactivate mark_page_lazyfree() moves @page to the inactive file list.* This is done to accelerate the reclaim of @page.
is_page_cache_freeable
__remove_mapping	Same as remove_mapping, but if the page is removed from the mapping, it* gets returned with a refcount of 0.
shrink_page_list	shrink_page_list() returns the number of reclaimed pages
page_mapping
page_mapping_file	For file cache pages, return the address_space, otherwise return NULL
do_wp_page	This routine handles present pages, when users try to write* to a shared page. It is done by copying the page to a new address* and decrementing the shared-page counter for the old page.* Note that this routine assumes that the protection checks have been
do_swap_page	We enter with non-exclusive mmap_sem (to exclude vma changes,* but allow concurrent faults), and pte mapped but not yet locked.* We return with pte unmapped and unlocked.* We return with the mmap_sem locked or unlocked in the same cases
try_to_unmap_one	@arg: enum ttu_flags will be passed to this argument
madvise_free_pte_range
swap_slot_free_notify
__swap_writepage
swap_readpage
swap_set_page_dirty
add_to_swap_cache	add_to_swap_cache resembles add_to_page_cache_locked on swapper_space,* but sets SwapCache flag and private instead of mapping and index.
__delete_from_swap_cache	This must be called only on pages that have* been verified to be in the swap cache.
free_swap_cache	If we are the only user, then try to free up the swap cache. * Its ok to check for PageSwapCache without the page lock* here because we are going to recheck again inside* try_to_free_swap() _with_ the lock.* - Marcelo
page_trans_huge_map_swapcount
reuse_swap_page	We can write to an anon page without COW if there are no other references* to it. And as a side-effect, free up its swap: because the old content* on disk will never be read, and seeking back there to write new content
try_to_free_swap	If swap is getting full, or if there are no more mappings of this page,* then try_to_free_swap is called to free its swap space.
get_ksm_page	get_ksm_page: checks if the page indicated by the stable node* is still its ksm page, despite having held no reference to it.* In which case we can trust the content of the page, and it* returns the gotten page; but if the page has now been zapped,
write_protect_page
reuse_ksm_page
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.
migrate_page_states	Copy the page to its new location
__split_huge_page_tail
__split_huge_page
can_split_huge_page	Racy check whether the huge page can be split
split_huge_page_to_list	This function splits huge page into normal pages. @page can point to any* subpage of huge page to split. Split doesn't change the position of @page.* Only caller must hold pin on the @page, otherwise split fails with -EBUSY.* The huge page must be locked.
deferred_split_huge_page
__collapse_huge_page_isolate
khugepaged_scan_pmd
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
hwpoison_user_mappings	Do all that is necessary to remove user space mappings. Unmap* the pages and send SIGBUS to the processes if the data was dirty.
memory_failure	memory_failure - Handle memory failure of a page.@pfn: Page Number of the corrupted page@flags: fine tune action taken* This function is called by the low level machine check code* of an architecture when it detects hardware memory corruption* of a page
