ZFS online deduplication is not comparable with on-demand dedup offered btrfs and xfs and is prohibitively expensive for many workloads.

The new block cloning still had data corruption bugs quite recently.

But it has de-duplication, with your logic no non-CoW FS should be in that list because they are not comparable.

It is still deduplication.

Chart should have a bloc dedup and file dedup separated columns if it is deemed non comparable.
