**Caller**
Name	Describe
pagecache_get_page	pagecache_get_page - find and get a page reference@mapping: the address_space to search@offset: the page index@fgp_flags: PCG flags@gfp_mask: gfp mask to use for the page cache data page allocation* Looks up the page cache slot at @mapping & @offset.
generic_file_buffered_read	generic_file_buffered_read - generic file read routine@iocb: the iocb to read@iter: data destination@written: already copied This is a generic file read routine, and uses the* mapping->a_ops->readpage() function for the actual low-level stuff.
lock_page_maybe_drop_mmap	lock_page_maybe_drop_mmap - lock the page, possibly dropping the mmap_sem@vmf - the vm_fault for this fault.@page - the page to lock.*@fpin - the pointer to the file we may pin (or is already pinned).
filemap_map_pages
read_cache_pages_invalidate_page	see if a page needs releasing upon read_cache_pages() failure* - the caller of read_cache_pages() may have set PG_private or PG_fscache* before calling, such as the NFS fs marking pages that are cached locally* on disk, thus we need to give the fs a
truncate_inode_pages_range	runcate_inode_pages_range - truncate range of pages specified by start & end byte offsets@mapping: mapping to truncate@lstart: offset from which to truncate@lend: offset to which to truncate (inclusive) Truncate the page cache, removing the pages that
invalidate_mapping_pages	validate_mapping_pages - Invalidate all the unlocked pages of one inode@mapping: the address_space which holds the pages to invalidate@start: the offset 'from' which to invalidate@end: the offset 'to' which to invalidate (inclusive) This function only
shrink_page_list	shrink_page_list() returns the number of reclaimed pages
__isolate_lru_page	Attempt to remove the specified page from its LRU. Only take this page* if it is of the appropriate PageActive status. Pages which are being* freed elsewhere are also ignored.* returns 0 on success, -ve errno on failure.
shrink_active_list
follow_page_pte
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
page_referenced	page_referenced - test if the page was referenced@page: the page to test@is_locked: caller holds lock on the page@memcg: target memory cgroup@vm_flags: collect encountered vma->vm_flags who actually referenced the page* Quick test_and_clear_referenced
madvise_cold_or_pageout_pte_range
madvise_free_pte_range
swap_readpage
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
__try_to_reclaim_swap	rns 1 if swap entry is freed
hugetlb_fault
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,
try_to_merge_one_page	ry_to_merge_one_page - take two pages and merge them into one@vma: the vma that holds the pte pointing to page@page: the PageAnon page that we want to replace with kpage*@kpage: the PageKsm page that we want to map instead of page,
cmp_and_merge_page	mp_and_merge_page - first see if page can be merged into the stable tree;* if not, compare checksum to previous and if it's the same, see if page can* be inserted into the unstable tree, or merged with a page already there and
isolate_movable_page
__unmap_and_move
unmap_and_move_huge_page	Counterpart of unmap_and_move_page() for hugepage migration
do_huge_pmd_wp_page
follow_trans_huge_pmd
do_huge_pmd_numa_page	NUMA hinting page fault entry point for trans huge pmds
madvise_free_huge_pmd	Return true if we do MADV_FREE successfully on entire pmd page.* Otherwise, return false.
deferred_split_scan
__collapse_huge_page_isolate
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.
trylock_zspage
z3fold_alloc	z3fold_alloc() - allocates a region of a given size@pool: z3fold pool from which to allocate@size: size in bytes of the desired allocation@gfp: gfp flags used if the pool needs to grow@handle: handle of the new allocation* This function will attempt
balloon_page_enqueue_one
balloon_page_list_dequeue	alloon_page_list_dequeue() - removes pages from balloon's page list and* returns a list of the pages.@b_dev_info: balloon device decriptor where we will grab a page from.@pages: pointer to the list of pages that would be returned to the caller.
