#
# DESCRIPTION:
#   Executing 'zfs upgrade' command succeeds, it should report
#   the current system version and list all old-version filesystems.
#   If no old-version filesystems be founded, it prints out
#   "All filesystems are formatted with the current version."
#
# STRATEGY:
# 1. Prepare a set of datasets which contain old-version and current version.
# 2. Execute 'zfs upgrade', verify return 0, and it prints out
#   the current system version and list all old-version filesystems.
# 3. Remove all old-version filesystems, then execute 'zfs upgrade' again,
#   verify return 0, and get the expected message.
