[ Upstream commit b61ac5b720 ]
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

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
