Jeff Layton c49f06ffab exfat: fs: pass the request_mask to generic_fillattr
generic_fillattr just fills in the entire stat struct indiscriminately
today, copying data from the inode. There is at least one attribute
(STATX_CHANGE_COOKIE) that can have side effects when it is reported,
and we're looking at adding more with the addition of multigrain
timestamps.

Add a request_mask argument to generic_fillattr and have most callers
just pass in the value that is passed to getattr. Have other callers
(e.g. ksmbd) just pass in STATX_BASIC_STATS. Also move the setting of
STATX_CHANGE_COOKIE into generic_fillattr.

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
