  35 # DESCRIPTION:
  36 # Create two directory trees in ZFS filesystem, and concurently rename
  37 # directory across the two trees. ZFS should be able to handle the race
  38 # situation.
  39 #
  40 # STRATEGY:
  41 # 1. Create a ZFS filesystem
  42 # 2. Make two directory tree in the zfs file system
