--- Comment #15 from Alexander Motin <mav@FreeBSD.org> ---
It seems makefs-generated ZFS images by skipping some optional dataset
structures activate code not used since before ancient zpool version 11 and
missing some locks.  I think https://github.com/openzfs/zfs/pull/16162 should
fix the problem.  Though I wonder whether/when ZFS will regenerate those
structures without explicit upgrade from the pre-11 pool version or will
forever use the old code.
