Is it Christmas already ? Thanks ! :)

I tried it on my 8-STABLE box (root zpool v15 on 2 mirrored vdevs with
an usb l2 cache). I checked-out CURRENT sources with svn, applied the
patch (it applied cleanly). Did not modify kernel config (no
debugging) or make.conf. buildworld, buildkernel, installkernel
INSTKERNNAME=CURRENT and rebooted in single-user mode with
kernel="CURRENT". No problem so far, the kernel displayed the good
freebsd/zpool/zfs version numbers, and it booted correctly in
single-user mode. But I had problems with userland v15 :
# mount
tank/freebsd on / (zfs, local, noatime, read-only)
devfs on /dev (devfs, local)
# zpool status
Assertion failed: (nvlist_lookup_uint64_array(nvroot,
ZPOOL_CONFIG_STATS, (uint64_t **)&vs, &vsc) == 0), file
/usr/src/cddl/lib/libzfs/../../../cddl/contrib/opensolaris/lib/libzfs/common/libzfs_status.c,
line 181.
pid 20 (zpool), uid 0: exited on signal 6
Abort trap

Am I missing something ?
