>Description:
Device entry for received from snapshot volume must be created, but not created.
>How-To-Repeat:
# zpool create tank `mdconfig -a -t swap -s 64m`
# zfs create -V 1M tank/vol1
# zfs snapshot tank/vol1 at snap
# ls /dev/zvol/tank
vol1            vol1 at snap
# zfs send tank/vol1 at snap | zfs receive tank/vol2
# ls /dev/zvol/tank
vol1            vol1 at snap <- there is no entries for vol2
# zpool export tank
# zpool import tank
# ls /dev/zvol/tank
vol1            vol1 at snap       vol2            vol2 at snap <- magic!
