**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.
account_page_dirtied	Helper function for set_page_dirty family.* Caller must hold lock_page_memcg().* NOTE: This relies on being atomic wrt interrupts.
account_page_cleaned	Helper function for deaccounting dirty page without writeback.* Caller must hold lock_page_memcg().
account_page_redirty	Call this whenever redirtying a page, to de-account the dirty counters* (NR_DIRTIED, WB_DIRTIED, tsk->nr_dirtied), so that they match the written* counters (NR_WRITTEN, WB_WRITTEN) in long term
__cancel_dirty_page	This cancels just the dirty bit on the kernel page itself, it does NOT* actually remove dirty bits on any mmap's that may be around
clear_page_dirty_for_io	Clear a page's dirty flag, while caring for dirty memory accounting.* Returns true if the page was previously dirty.* This is for preparing to put the page under writeout. We leave the page* tagged as dirty in the xarray so that a concurrent write-for-sync
vma_wants_writenotify	Some shared mappings will want the pages marked read-only* to track write events. If so, we'll downgrade vm_page_prot* to the private version (using protection_map[] without the* VM_SHARED bit).
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.
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.
