名称描述
rotate_reclaimable_pageWriteback 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.
__lru_cache_add
deactivate_file_pagedeactivate_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_pagedeactivate_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_lazyfreemark_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.
truncate_inode_pages_rangeruncate_inode_pages_range - truncate range of pages specified by start & end byte offsets*@mapping: mapping to truncate*@lstart: offset from which to truncate*@lend: offset to which to truncate (inclusive)* Truncate the page cache, removing the pages that
__putback_lru_fast_preparePrepare page for fast batched LRU putback via putback_lru_evictable_pagevec()* The fast path is available only for evictable pages with single mapping.* Then we can bypass the per-cpu pvec and get better performance.
__munlock_pagevecMunlock a batch of pages from the same zone* The work is split to two main phases
__munlock_pagevec_fillFill up pagevec for __munlock_pagevec using pte walk* The function expects that the struct page corresponding to @start address is* a non-TPH page already pinned and in the @pvec, and that it belongs to @zone
munlock_vma_pages_rangemunlock_vma_pages_range() - munlock all pages in the vma range.'*@vma - vma containing range to be munlock()ed.*@start - start address in @vma of the range*@end - end of range in @vma.* For mremap(), munmap() and exit().* Called with @vma VM_LOCKED.
