名称 | 描述 |
---|---|
pagevec_move_tail_fn | |
rotate_reclaimable_page | Writeback is about to end against a page which has been marked for immediate* reclaim. If it still appears to be reclaimable, move it to the tail of the* inactive list. |
__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_cache_add | lru_cache_add - add a page to a page list*@page: the page to be added to the LRU.* Queue the page for addition to the LRU via pagevec. The decision on whether* to add the page to the [in]active [file|anon] list is deferred until the* pagevec is drained |
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 | |
lru_lazyfree_fn | |
deactivate_file_page | deactivate_file_page - forcefully deactivate a file page*@page: page to deactivate* This function hints the VM that @page is a good reclaim candidate,* for example if its invalidation fails due to the page being dirty* or under writeback. |
deactivate_page | deactivate_page - deactivate a page*@page: page to deactivate* deactivate_page() moves @page to the inactive list if @page was on the active* list and was not an unevictable page. This is done to accelerate the reclaim* of @page. |
mark_page_lazyfree | mark_page_lazyfree - make an anon page lazyfree*@page: page to deactivate* mark_page_lazyfree() moves @page to the inactive file list.* This is done to accelerate the reclaim of @page. |
lru_add_page_tail | sed by __split_huge_page_refcount() |
shrink_page_list | shrink_page_list() returns the number of reclaimed pages |
reclaim_clean_pages_from_list | |
__isolate_lru_page | Attempt to remove the specified page from its LRU. Only take this page* if it is of the appropriate PageActive status. Pages which are being* freed elsewhere are also ignored.* returns 0 on success, -ve errno on failure. |
check_move_unevictable_pages | heck_move_unevictable_pages - check pages for evictability and move to* appropriate zone lru list*@pvec: pagevec with lru pages to check* Checks pages for evictability, if an evictable page is in the unevictable |
clear_page_mlock | LRU accounting for clear_page_mlock() |
__munlock_isolation_failed | Accounting for page isolation fail during munlock* Performs accounting when page isolation fails in munlock. There is nothing* else to do because it means some other task has already removed the page* from the LRU |
madvise_cold_or_pageout_pte_range | |
migrate_page_states | Copy the page to its new location |
page_off_lru | page_off_lru - which LRU list was page on? clearing its lru flags.*@page: the page to test* Returns the LRU list a page was on, as an index into the array of LRU* lists; and clears its Unevictable or Active flags, ready for freeing. |
page_lru | page_lru - which LRU list should a page be on?*@page: the page to test* Returns the LRU list a page should be on, as an index* into the array of LRU lists. |
