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.
