Takashi Iwai 0d2005c28d exfat: Expand exfat_err() and co directly to pr_*() macro 
Currently the error and info messages handled by exfat_err() and co
are tossed to exfat_msg() function that does nothing but passes the
strings with printk() invocation.  Not only that this is more overhead
by the indirect calls, but also this makes harder to extend for the
debug print usage; because of the direct printk() call, you cannot
make it for dynamic debug or without debug like the standard helpers
such as pr_debug() or dev_dbg().

For addressing the problem, this patch replaces exfat_*() macro to
expand to pr_*() directly.  Along with it, add the new exfat_debug()
macro that is expanded to pr_debug() (which output can be gracefully
suppressed via dyndbg).

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
