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.
