4.9-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit b61ac5b720146c619c7cdf17eff2551b934399e5 ]
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
