struct page *	page

**调用者**
名称	描述
uprobe_write_opcode	NOTE:* Expect the breakpoint instruction to be the smallest size instruction for* the architecture
__put_page
rotate_reclaimable_page	Writeback is about to end against a page which has been marked for immediate* reclaim. If it still appears to be reclaimable, move it to the tail of the* inactive list.
__lru_cache_add
deactivate_file_page	deactivate_file_page - forcefully deactivate a file page@page: page to deactivate This function hints the VM that @page is a good reclaim candidate,* for example if its invalidation fails due to the page being dirty* or under writeback.
deactivate_page	deactivate_page - deactivate a page@page: page to deactivate deactivate_page() moves @page to the inactive list if @page was on the active* list and was not an unevictable page. This is done to accelerate the reclaim* of @page.
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.
release_pages	lease_pages - batched put_page()@pages: array of pages to release@nr: number of pages* Decrement the reference count on all the pages in @pages. If it* fell to zero, remove the page from the LRU and free it.
lru_add_page_tail	sed by __split_huge_page_refcount()
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
page_mapped	Return true if this page is mapped into pagetables.* For compound page it returns true if any subpage of compound page is mapped.
isolate_freepages_block	Isolate free pages onto a private freelist. If @strict is true, will abort* returning 0 on any invalid PFNs or non-free pages inside of the pageblock* (even though it may still end up isolating some pages).
isolate_migratepages_block	solate_migratepages_block() - isolate all migrate-able pages within* a single pageblock@cc: Compaction control structure.@low_pfn: The first PFN to isolate*@end_pfn: The one-past-the-last PFN to isolate, within same pageblock
__dump_page
kobjsize	Return the total memory allocated for this pointer, not* just what the caller asked for.* Doesn't have to be accurate, i.e. may have races.
do_numa_page
mlock_vma_page	Mark page as mlocked if not already.* If page on LRU, isolate and putback to move to unevictable list.
try_to_munlock	ry_to_munlock - try to munlock a page@page: the page to be munlocked Called from munlock code. Checks all of the VMAs mapping the page* to make sure nobody else has this page mlocked. The page will be
free_pages_prepare
split_page	split_page takes a non-compound higher-order page, and splits it into* n (1<
PageHuge	PageHuge() only returns true for hugetlbfs pages, but not for normal or* transparent huge pages. See the PageTransHuge() documentation for more* details.
build_detached_freelist	This function progressively scans the array with free objects (with* a limited look ahead) and extract objects belonging to the same* page. It builds a detached freelist directly within the given* page/objects. This can happen without any need for
__ksize
kfree	释放内存
__do_huge_pmd_anonymous_page
do_huge_pmd_wp_page
follow_trans_huge_pmd
total_mapcount
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.
__collapse_huge_page_isolate
khugepaged_scan_pmd
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
bio_release_pages
bio_set_pages_dirty	_set_pages_dirty() will mark all the bio's pages as dirty.

PageTransCompound	PageTransCompound returns true for both transparent huge pages* and hugetlbfs pages, so it should only be called when it's known* that hugetlbfs pages aren't involved.
compound_mapcount
page_mapcount
basepage_index	Return page->index in PAGE_SIZE units
