struct pagevec *	pvec

**调用者**
名称	描述
page_cache_delete_batch	page_cache_delete_batch - delete several pages from page cache@mapping: the mapping to which pages belong@pvec: pagevec with pages to delete* The function walks over mapping->i_pages and removes pages passed in @pvec* from the mapping
delete_from_page_cache_batch
pagevec_lru_move_fn
__lru_cache_activate_page
lru_add_drain_cpu	Drain pages out of the cpu's pagevecs.* Either "cpu" is the current CPU, and preemption has already been* disabled; or "cpu" is being hot-unplugged, and is already dead.
__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
pagevec_lookup_entries	pagevec_lookup_entries - gang pagecache lookup@pvec: Where the resulting entries are placed@mapping: The address_space to search@start: The starting entry index@nr_entries: The maximum number of pages*@indices: The cache indices corresponding to the
pagevec_remove_exceptionals	pagevec_remove_exceptionals - pagevec exceptionals pruning@pvec: The pagevec to prune pagevec_lookup_entries() fills both pages and exceptional radix* tree entries into the pagevec
pagevec_lookup_range	pagevec_lookup_range - gang pagecache lookup@pvec: Where the resulting pages are placed@mapping: The address_space to search@start: The starting page index@end: The final page index* pagevec_lookup_range() will search for & return a group of up to
pagevec_lookup_range_tag
pagevec_lookup_range_nr_tag
truncate_exceptional_pvec_entries	Unconditionally remove exceptional entries. Usually called from truncate* path. Note that the pagevec may be altered by this function by removing* exceptional entries similar to what pagevec_remove_exceptionals does.
truncate_inode_pages_range	runcate_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
invalidate_mapping_pages	validate_mapping_pages - Invalidate all the unlocked pages of one inode@mapping: the address_space which holds the pages to invalidate@start: the offset 'from' which to invalidate@end: the offset 'to' which to invalidate (inclusive) This function only
invalidate_inode_pages2_range	validate_inode_pages2_range - remove range of pages from an address_space@mapping: the address_space@start: the page offset 'from' which to invalidate@end: the page offset 'to' which to invalidate (inclusive) Any pages which are found to be mapped
__putback_lru_fast	Putback multiple evictable pages to the LRU* Batched putback of evictable pages that bypasses the per-cpu pvec. Some of* the pages might have meanwhile become unevictable but that is OK.
__munlock_pagevec	Munlock a batch of pages from the same zone* The work is split to two main phases
clean_bdev_aliases	lean_bdev_aliases: clean a range of buffers in block device@bdev: Block device to clean buffers in@block: Start of a range of blocks to clean@len: Number of blocks to clean We are taking a range of blocks for data and we don't want writeback of any*
