Yuezhang Mo 3ad149047d exfat: fix ctime is not updated 
Commit 4c72a36edd54 removed attr_copy() from exfat_set_attr().
It causes xfstests generic/221 to fail. In xfstests generic/221,
it tests ctime should be updated even if futimens() update atime
only. But in this case, ctime will not be updated if attr_copy()
is removed.

attr_copy() may also update other attributes, and removing it may
cause other bugs, so this commit restores to call attr_copy() in
exfat_set_attr().

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
