There is a new pull request by zdykstra against master on the void-packages repository

https://github.com/zdykstra/void-packages zfs-2.1.6
https://github.com/void-linux/void-packages/pull/39684

zfs: update to 2.1.6.
#### Testing the changes
- I tested the changes in this PR: **YES**

This could use testing by users that do NOT have root-on-ZFS for their ZFS usage. Tested locally on x86_64, no native encryption, root-on-ZFS.
