Start on kernel 5.7, exfat is include in fs/exfat/

Start on kernel 5.4, exfat is include in drivers/staging/exfat

Linux non-fuse read/write kernel driver for the exFAT, FAT12, FAT16 and vfat (FAT32) file systems.<br /> Originally ported from Android kernel v3.0.

Kudos to ksv1986 for the mutex patch!<br /> Thanks to JackNorris for being awesome and providing the clear_inode() patch.<br /> <br /> Big thanks to lqs for completing the driver!<br /> Big thanks to benpicco for fixing 3.11.y compatibility!<br />

Special thanks to github user AndreiLux for spreading the word about the leak!<br />

make
sudo make install

To load the driver manually, run this as root:

modprobe exfat

You may also specify custom toolchains by using CROSS_COMPILE flag, in my case:

CROSS_COMPILE=../dorimanx-SG2-I9100-Kernel/android-toolchain/bin/arm-eabi-

Let's take [linux] as the path to your kernel source dir...

cd [linux]
cp -rvf exfat-nofuse [linux]/fs/exfat

edit [linux]/fs/Kconfig

 menu "DOS/FAT/NT Filesystems"
  
  source "fs/fat/Kconfig"
 +source "fs/exfat/Kconfig"
  source "fs/ntfs/Kconfig"
  
 endmenu  

edit [linux]/fs/Makefile

  obj-$(CONFIG_FAT_FS)    += fat/
 +obj-$(CONFIG_EXFAT_FS)  += exfat/
  obj-$(CONFIG_BFS_FS)    += bfs/

cd [linux]
make menuconfig

Go to:

File systems > DOS/FAT/NT check exfat as MODULE (M) <br/> (437) Default codepage for exFAT <br/> (utf8) Default iocharset for exFAT <br/>

ESC to main menu <br/> Save an Alternate Configuration File <br/> ESC ESC <br/>

build your kernel

Have fun.
