Tetsuhiro Kohada 117088f39d exfat: remove EXFAT_SB_DIRTY flag 
This flag is set/reset in exfat_put_super()/exfat_sync_fs()
to avoid sync_blockdev().
- exfat_put_super():
Before calling this, the VFS has already called sync_filesystem(),
so sync is never performed here.
- exfat_sync_fs():
After calling this, the VFS calls sync_blockdev(), so, it is meaningless
to check EXFAT_SB_DIRTY or to bypass sync_blockdev() here.

Remove the EXFAT_SB_DIRTY check to ensure synchronization.
And remove the code related to the flag.

exFAT filesystem

This is the exfat filesystem for support from the linux 4.1 kernel to the latest kernel.

Installing as a stand-alone module

Install prerequisite package for Fedora, RHEL:

	yum install kernel-devel-$(uname -r)

Build step:

	make
	sudo make install

To load the driver manually, run this as root:

	modprobe exfat

Installing as a part of the kernel

  1. Let's take [linux] as the path to your kernel source dir.
	cd [linux]
	cp -ar exfat [linux]/fs/
  1. edit [linux]/fs/Kconfig
	source "fs/fat/Kconfig"
	+source "fs/exfat/Kconfig"
	source "fs/ntfs/Kconfig"
  1. edit [linux]/fs/Makefile
	obj-$(CONFIG_FAT_FS)          += fat/
	+obj-$(CONFIG_EXFAT_FS)       += exfat/
	obj-$(CONFIG_BFS_FS)          += bfs/
  1. make menuconfig and set exfat
