f2fs: move dir data flush to write checkpoint process
[ 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
