Caller
NameDescribe
page_cache_delete_batchpage_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_cpuDrain 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_releaseThe 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_entriespagevec_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_exceptionalspagevec_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_rangepagevec_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_entriesUnconditionally 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_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
invalidate_mapping_pagesvalidate_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_rangevalidate_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_fastPutback 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_pagevecMunlock a batch of pages from the same zone* The work is split to two main phases
clean_bdev_aliaseslean_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*
