You shouldn't need to build the kernel module yourself - that documentation is only in case we need to do this again (and may be useful for any other modules we need to compile).

# building the kernel module

(this list of dependencies may be incomplete)
sudo apt install build-essential bc

cd /usr/src/kernel
sudo make oldconfig

cd ~
git clone --depth 1 --branch xilinx-v2020.1 https://github.com/Xilinx/linux-xlnx.git
cd linux-xlnx

cp /usr/src/kernel/.config .
cp /usr/src/kernel/Module.symvers .

"make kernelversion" and "uname -r" should print the same thing, and "./scripts/setlocalversion" should print "-xilinx-v2020.1"

make menuconfig
in File systems->FUSE: put an <M> in FUSE.
in General architecture-dependent options: remove the <*> in Stack Protector buffer overflow detection.
Save and exit.

make scripts prepare modules_prepare

make -C . M=fs/fuse

# installing the kernel module

sudo mkdir /lib/modules/5.4.0-xilinx-v2020.1/kernel/fs/fuse/
sudo cp fs/fuse/fuse.ko /lib/modules/5.4.0-xilinx-v2020.1/kernel/fs/fuse/
sudo depmod

sudo modprobe fuse

I think the module will be loaded automatically at boot but if not, you will need to do some more configuration or run "modprobe fuse" after each boot.

# sshfs

sudo apt install sshfs

mkdir mountpoint

mount the remote directory "/data" on the local directory "mountpoint":
sshfs sensei@jiji.fnal.gov:/data mountpoint

unmount:
fusermount -u mountpoint
