>Description:
Importing a ZFS pool created by OpenSolaris with filesystems enabling sharesmb, then running "du" on the filesystem causes panic: zfs_fuid_map_id.

This looks like simliar to:
kern/145778: [zfs] [panic] panic in zfs_fuid_map_id (known issue fixed in opensolaris)

>How-To-Repeat:
Create a ZFS pool on OpenSolaris (2009.06)  (zfs v14).
Create a filesystem.
set sharesmb=ON

import the ZFS pool on FreeBSD
run "du" on the mounted filesystem, which attribute has "sharesmb=ON"
