__generic_file_write_iter	__generic_file_write_iter - write data to a file@iocb: IO state structure (file, offset, etc.)@from: iov_iter with data to write* This function does all the work needed for actually writing data to a* file
generic_fadvise	POSIX_FADV_WILLNEED could set PG_Referenced, and POSIX_FADV_NOREUSE could* deactivate the pages and clear PG_Referenced.
balance_dirty_pages_ratelimited	alance_dirty_pages_ratelimited - balance dirty memory state@mapping: address_space which was dirtied Processes which are dirtying memory should call in here once for each page* which was newly dirtied. The function will periodically check the system's
write_cache_pages	write_cache_pages - walk the list of dirty pages of the given address space and write all of them

__test_set_page_writeback
wait_for_stable_page	wait_for_stable_page() - wait for writeback to finish, if necessary.@page: The page to wait on. This function determines if the given page is related to a backing device* that requires page contents to be held stable during writeback. If so, then
file_ra_state_init	Initialise a struct file's readahead state. Assumes that the caller has* memset *ra to zero.
force_page_cache_readahead	Chunk the readahead into 2 megabyte units, so that we don't pin too much* memory at once.
