Name	Describe
page_cache_delete	Lock ordering:* ->i_mmap_rwsem (truncate_pagecache)* ->private_lock (__free_pte->__set_page_dirty_buffers)* ->swap_lock (exclusive_swap_page, others)* ->i_pages lock* ->i_mutex* ->i_mmap_rwsem (truncate->unmap_mapping_range)* ->mmap_sem* ->i_mmap_rwsem
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
free_compound_page	Higher-order pages are called "compound pages". They are structured thusly:* The first PAGE_SIZE page is called the "head page" and have PG_head set.* The remaining PAGE_SIZE pages are called "tail pages". PageTail() is encoded
free_pages_prepare
__page_frag_cache_drain
page_frag_free	Frees a page fragment allocated out of either a compound or order 0 page.
add_to_swap_cache	add_to_swap_cache resembles add_to_page_cache_locked on swapper_space,* but sets SwapCache flag and private instead of mapping and index.
__basepage_index
kfree
__free_slab
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
kfree

shrink_huge_zero_page_scan
