Bug Description
In the /etc/fstab of installed ubuntu bionic system I specified compress=zstd for the btrfs root filesytem
After runing 'sudo btrfs filesystem defragment -r -czstd /' the system booted to a grub shell. I could boot again by running 'sudo btrfs filesystem defragment -r -clzo /' and specifying compress=lzo in the /etc/fstab.
There is also a new bug in the btrfs tools:
btrfs does recognize the option '-clzo' but not '-c lzo'.

I wonder if I should be disabling zstd support in btrfs-progs, if we cannot boot them.
