Yes. Your patch got fix this problem.

I tried 5.3-BETA4 09/18 and got success.

  # kldload geom_uzip
  # mdconfig -a -f image.cloop
  ...
  # mount_cd9660 /dev/md0.uzip /mnt
  # ls /mnt
  ...
  # umount /mnt
  # mdconfig -d -u md0
  # kldunload geom_uzip

I think this patch is simple and very good. Please merge it :)
