  37 # DESCRIPTION:
  38 # When set property devices=off on file system, device files cannot be used
  39 # in this file system.
  40 #
  41 # STRATEGY:
  42 # 1. Create pool and file system.
  43 # 2. Set devices=off on this file system.
  44 # 3. Separately create block device file and character file.
  45 # 4. Separately read from those two device files.
  46 # 5. Check the return value, and make sure it failed.
