SVN rev 196965 on 2009-09-08 08:54:15Z by pjd
Fix reference count leak for a case where snapshot's mount point is updated.
Such situation is not supported.
This problem was triggered by something like this:
# zpool create tank da0
# zfs snapshot tank@snap
# cd /tank/.zfs/snapshot/snap (this will mount the snapshot)
# cd
# mount -u nosuid /tank/.zfs/snapshot/snap (refcount leak)
# zpool export tank
cannot export 'tank': pool is busy
