[Dietmar Maurer]

> now it is possible to make a snapshot and mount it to backup it.

This works for me without this patch? For example:

# pct config 102
arch: amd64
cpulimit: 1
cpuunits: 1024
hostname: fastboot
memory: 1152
net0: bridge=vmbr0,hwaddr=3A:ED:32:F0:51:6E,ip=dhcp,name=eth0,type=veth
ostype: debian
rootfs: subpool:subvol-102-disk-1,size=5G # this is a zfspool
swap: 512
