I would like to know if there are any plans to support ZFS deduplication.
Considering that ZFS introduced block cloning support in version 2.2.0, I believe incorporating ZFS deduplication functionality into it would be very meaningful.

zfs-2.2.0-rc3
zfs-2.2.0-rc2

Based on this page it doesn't look like ZFS dedupe_file_range does anything other than return EOPNOTSUPP or ENOTTY. Unfortunately we wouldn't be able to support dedupe on ZFS until it supports those calls.
