A separate patch that is currently a pull request > for OpenZFS, calls this function to fix the problem. May the same/similar fix like for ZFS be needed / useful for nullfs mounted stuff? I have a ZFS dataset which is mounted via nullfs into a jail. This nullfs-mount is then exported via samba. In samba I have the shadow-copy stuff enabled, but it doesn't work, as the jails can't access the snapshot.
