lru_add_drain

**调用者**
名称	描述
lru_add_drain_all
__pagevec_release	The pages which we're about to release may be in the deferred lru-addition* queues. That would prevent them from really being freed right now. That's* OK from a correctness point of view but is inefficient - those pages may be
shrink_inactive_list	shrink_inactive_list() is a helper for shrink_node(). It returns the number* of reclaimed pages
shrink_active_list
follow_page_pte
zap_page_range	zap_page_range - remove user pages in a given range@vma: vm_area_struct holding the applicable pages@start: starting address of pages to zap@size: number of bytes to zap Caller must protect the VMA list
zap_page_range_single	zap_page_range_single - remove user pages in a given range@vma: vm_area_struct holding the applicable pages@address: starting address of pages to zap@size: number of bytes to zap@details: details of shared cache invalidation
unmap_region
exit_mmap	Release all mmaps.
madvise_cold
madvise_pageout
madvise_free_single_vma
free_pages_and_swap_cache	Passed an array of pages, drop them all from swapcache and then release* them. They are removed from the LRU and freed if this is their last use.
swap_cluster_readahead	swap_cluster_readahead - swap in pages in hope we need them soon@entry: swap entry of this memory@gfp_mask: memory allocation flags@vmf: fault information Returns the struct page for entry and addr, after queueing swapin.
swap_vma_readahead	swap_vma_readahead - swap in pages in hope we need them soon@entry: swap entry of this memory@gfp_mask: memory allocation flags@vmf: fault information Returns the struct page for entry and addr, after queueing swapin.* Primitive swap readahead code
migrate_prep_local	Do the necessary work of migrate_prep but not if it involves other CPUs
follow_trans_huge_pmd
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.
memfd_tag_pins
generic_fadvise	POSIX_FADV_WILLNEED could set PG_Referenced, and POSIX_FADV_NOREUSE could* deactivate the pages and clear PG_Referenced.
shift_arg_pages	During bprm_mm_init(), we create a temporary stack at STACK_TOP_MAX. Once* the binfmt code determines where the new stack should reside, we shift it to* its final location. The process proceeds as follows:* 1) Use shift to calculate the new vma endpoints.
