read_pages
shrink_lruvec
SYSCALL_DEFINE3	The madvise(2) system call
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
blkdev_issue_discard	lkdev_issue_discard - queue a discard@bdev: blockdev to issue discard for@sector: start sector@nr_sects: number of sectors to discard@gfp_mask: memory allocation flags (for bio_alloc)@flags: BLKDEV_DISCARD_ flags to control behaviour* Description:
blkdev_issue_write_same	lkdev_issue_write_same - queue a write same operation@bdev: target blockdev@sector: start sector@nr_sects: number of sectors to write@gfp_mask: memory allocation flags (for bio_alloc)@page: page containing data Description:
blkdev_issue_zeroout	lkdev_issue_zeroout - zero-fill a block range@bdev: blockdev to write@sector: start sector@nr_sects: number of sectors to write@gfp_mask: memory allocation flags (for bio_alloc)@flags: controls detailed behavior Description:* Zero-fill a block
blk_throtl_dispatch_work_fn	lk_throtl_dispatch_work_fn - work function for throtl_data->dispatch_work@work: work item being executed This function is queued for execution when bio's reach the bio_lists[]* of throtl_data->service_queue. Those bio's are ready and issued by this
wb_writeback	Explicit flushing or periodic writeback of "old" data
fsync_buffers_list
__blkdev_direct_IO
blkdev_write_iter	Write data to the block device. Only intended for the block device itself* and the raw driver which basically is a fake block device.* Does not take i_mutex for the write and thus is not for general purpose* use.
do_blockdev_direct_IO	This is a library function for use by filesystem drivers
mpage_writepages	mpage_writepages - walk the list of dirty pages of the given address space & writepage() all of them@mapping: address space structure to write@wbc: subtract the number of written pages from *@wbc->nr_to_write
SYSCALL_DEFINE3	sys_io_submit:* Queue the nr iocbs pointed to by iocbpp for processing
COMPAT_SYSCALL_DEFINE3
io_submit_state_end	Batched submission is done, ensure local IO is flushed out.
iomap_dio_rw	map_dio_rw() always completes O_[D]SYNC writes regardless of whether the IO* is being issued as AIO or not. This allows us to optimise pure data writes* to use REQ_FUA rather than requiring generic_write_sync() to issue a* REQ_FLUSH post write
generic_writepages	generic_writepages - walk the list of dirty pages of the given address space and writepage() all of them
