Bug description:
=== SRU Justification, Xenial ==
An attempt to mount an already mounted zfs dataset should return a new
mount referencing the existing super block, but instead it returns an
error. Operations such as bind mounts and unsharing mount namespaces
create new mounts for the sb, which can cause operations to fail which
involve unmounting and remounting the dataset.
== Fix ==
Backport of upstream fix https://trello.com/c/l89Ygj28/352-allow-
multiple-mounts-of-zfs-datasets to allow multiple mounts
This fix from Seth addresses this issue
== Regression potential ==
Like all backports, this has a potential to be incorrectly backported
and break the ZFS mounting. However, any breakage should be picked up
via the ZFS smoke tests that thoroughly exercise mounting/dismounting
options. At worst, the mounting won't work, but this has been tested,
so I doubt this is a possibility.
