The patch is ok for stable.
now I get for the pool with my root:
[root@morzine libzpool]# zdb rpool
version=13
name='rpool'
state=0
txg=959
pool_guid=17669857244588609348

children[0]
type='mirror'
id=0
guid=3225603179255348056
metaslab_array=23
metaslab_shift=28
ashift=9

is_log=0
children[0]

whole_disk=0
children[1]
type='disk'
id=1
guid=2736169600077218893
path='/dev/da1p2'
whole_disk=0
WARNING: pool 'rpool' could not be loaded as it was last accessed by
another system (host: unset hostid: 0x8a08f344). See:
http://www.sun.com/msg/ZFS-8000-EY
zdb: can't open rpool: No such file or directory
But rpool have been used for many boot now - strange ...
Thanks for your patch and time
