__activate_page
mark_page_accessed	Mark a page as having seen activity.* inactive,unreferenced -> inactive,referenced* inactive,referenced -> active,unreferenced* active,unreferenced -> active,referenced* When a newly allocated page is not yet visible, so safe for non-atomic ops,
lru_deactivate_file_fn	If the page can not be invalidated, it is moved to the* inactive list to speed up its reclaim. It is moved to the* head of the list, rather than the tail, to give the flusher* threads some time to write it out, as this is much more
lru_deactivate_fn
__pagevec_lru_add_fn
__remove_mapping	Same as remove_mapping, but if the page is removed from the mapping, it* gets returned with a refcount of 0.
page_check_dirty_writeback	Check if a page is dirty or under writeback
shrink_page_list	shrink_page_list() returns the number of reclaimed pages
reclaim_clean_pages_from_list
shrink_active_list
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
check_and_migrate_cma_pages
change_pte_range
migrate_page_add
putback_movable_pages	Put previously isolated pages back onto the appropriate lists* from where they were once taken off for compaction/migration.* This function shall be used whenever the isolated pageset has been* built from lru, balloon, hugetlbfs page
unmap_and_move	Obtain the lock on page, remove all ptes and migrate the page* to the newly allocated page in newpage.

__collapse_huge_page_isolate
__soft_offline_page
