f2fs: move dir data flush to write checkpoint process
This patch move dir data flush to write checkpoint process, by doing this, it may reduce some time for dir fsync. pre: -f2fs_do_sync_file enter -file_write_and_wait_range <- flush & wait -write_checkpoint -do_checkpoint <- wait all -f2fs_do_sync_file exit now: -f2fs_do_sync_file enter -write_checkpoint -block_operations <- flush dir & no wait -do_checkpoint <- wait all -f2fs_do_sync_file exit Signed-off-by: Yunlei He <heyunlei@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
