**调用者**
名称	描述
reclaim_pages
list_lru_add
list_lru_del
new_non_cma_page
do_numa_page
change_pte_range
show_numa_info
move_freepages	Move the free pages in a range to the free lists of the requested type.* Note that start_page and end_pages are not aligned on a pageblock* boundary. If alignment is required, use move_freepages_block()
enqueue_huge_page
update_and_free_page
__free_huge_page
alloc_fresh_huge_page	Common helper to allocate a fresh hugetlb page. All specific allocators* should use this function to get new hugetlb pages
dissolve_free_huge_page	Dissolve a given free hugepage into free buddy pages. This function does* nothing for in-use hugepages and non-hugepages.* This function returns values like below:* -EBUSY: failed to dissolved free hugepages or the hugepage is in-use
alloc_surplus_huge_page	Allocates a fresh surplus page from the page allocator.
gather_bootmem_prealloc	Put bootmem huge pages into the standard lists after mem_map is up
move_hugetlb_state
queue_pages_required	Check if the page's nid is in qp->nmask.* If MPOL_MF_INVERT is set in qp->flags, check if the nid is* in the invert of qp->nmask.
lookup_node
alloc_page_interleave	Allocate a page in interleaved policy.Own path because it needs to do special accounting.
mpol_misplaced	mpol_misplaced - check whether current page node is valid in policy@page: page to be checked@vma: vm area where page mapped@addr: virtual address where page mapped Lookup current policy node id for vma,addr and "compare to" page's* node id
slob_alloc	slob_alloc: entry point into the slob allocator.
unstable_tree_search_insert	stable_tree_search_insert - search for identical page,* else insert rmap_item into the unstable tree.* This function searches for a page in the unstable tree identical to the* page currently being scanned; and if no identical page is found in the
cache_free_pfmemalloc
cache_free_alien
cache_grow_begin	Grow (by 1) the number of slabs within a cache. This is called by* kmem_cache_alloc() when there are no active objs left in a cache.
cache_grow_end
fallback_alloc	Fallback function if there was no memory available and no objects on a* certain node and fall back is permitted. First we scan all the* available node for available objects. If that fails then we* perform an allocation without specifying a node
allocate_slab
discard_slab
deactivate_slab	Remove the cpu slab
node_match	Check if the objects in a per cpu structure fit numa* locality expectations.
__slab_free	Slow path handling. This may still be called frequently since objects* have a longer lifetime than the cpu slabs in most processing loads.* So we still attempt to reduce cache line usage. Just take the slab* lock and free the item
early_kmem_cache_node_alloc	No kmalloc_node yet so do it by hand. We know that this is the first* slab on the node for this slabcache. There are no concurrent accesses* possible.* Note that this function only works on the kmem_cache_node* when allocating for the kmem_cache_node
add_page_for_migration	Resolves the given address to a struct page, isolates it from the LRU and* puts it to the given pagelist
do_pages_stat_array	Determine the nodes of an array of pages and store it in an array of status.
get_deferred_split_queue
do_huge_pmd_wp_page_fallback
do_huge_pmd_numa_page	NUMA hinting page fault entry point for trans huge pmds
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
khugepaged_scan_pmd
mem_cgroup_page_nodeinfo
soft_limit_tree_from_page
mem_cgroup_try_charge_delay
shake_page	When a unknown page type is encountered drain as many buffers as possible* in the hope to turn the page into a LRU or free page, which we can handle.
new_page
kmemleak_scan	Scan data sections and all the referenced memory blocks allocated via the* kernel's standard allocators. This function must be called with the* scan_mutex held.
lookup_page_ext
page_cpupid_xchg_last
page_cpupid_last
page_zone
page_pgdat
