enum vm_event_item	item

**调用者**
名称	描述
filemap_fault	lemap_fault - read in file data for page fault handling@vmf: struct vm_fault containing details of the fault filemap_fault() is invoked via the vma operations vector for a* mapped memory region to read in file data during a page fault
__oom_kill_process
lru_cache_add_active_or_unevictable	lru_cache_add_active_or_unevictable@page: the page to be added to LRU@vma: vma in which page is mapped for determining reclaimability* Place @page on the active or unevictable LRU list, depending on its* evictability
__pagevec_lru_add_fn
shrink_page_list	shrink_page_list() returns the number of reclaimed pages
throttle_direct_reclaim	Throttle direct reclaimers if backing storage is backed by the network* and the PFMEMALLOC reserve for the preferred node is getting dangerously* depleted. kswapd will continue to make progress and wake the processes* when the low watermark is reached.
balance_pgdat	For kswapd, balance_pgdat() will reclaim pages across a node from zones* that are eligible for use by the caller until at least one zone is* balanced.* Returns the order kswapd finished reclaiming at.
kswapd_try_to_sleep
node_reclaim
do_swap_page	We enter with non-exclusive mmap_sem (to exclude vma changes,* but allow concurrent faults), and pte mapped but not yet locked.* We return with pte unmapped and unlocked.* We return with the mmap_sem locked or unlocked in the same cases
handle_mm_fault	By the time we get here, we already hold the mm semaphore* The mmap_sem may have been released depending on flags and our* return value. See filemap_fault() and __lock_page_or_retry().
clear_page_mlock	LRU accounting for clear_page_mlock()
mlock_vma_page	Mark page as mlocked if not already.* If page on LRU, isolate and putback to move to unevictable list.
__munlock_isolated_page	Finish munlock after successful page isolation* Page must be locked. This is a wrapper for try_to_munlock()* and putback_lru_page() with munlock accounting.
count_swpout_vm_event
__swap_writepage
swap_readpage
lookup_swap_cache	Lookup a swap entry in the swap cache. A found page will be returned* unlocked and with its refcount incremented - we rely on the kernel* lock getting page table operations atomic even if we drop the page* lock before returning.
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

__do_huge_pmd_anonymous_page
do_huge_pmd_anonymous_page
do_huge_pmd_wp_page
__split_huge_pmd_locked
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.
