  35 # DESCRIPTION:
  36 #       Re-creating zfs files, 'zfs unmount' still succeed.
  37 #
  38 # STRATEGY:
  39 #       1. Create pool and filesystem.
  40 #       2. Recreating the same file in this fs for a while, then breaking out.
  41 #       3. Verify the filesystem can be unmount successfully.
