# DESCRIPTION:
#   Executing 'zfs upgrade -r [-V version] filesystem' command succeeds,
#   it upgrade filesystem recursively to specific or current version.
#
# STRATEGY:
# 1. Prepare a set of datasets which contain old-version and current version.
# 2. Execute 'zfs upgrade -r [-V version] filesystem', verify return 0,
# 3. Verify the filesystem be updated recursively as expected.
