#
# DESCRIPTION:
# Verify that 'find' command with '-ls' and '-acl' options supports ZFS ACL
#
# STRATEGY:
# 1. Create 5 files and 5 directories in zfs filesystem
# 2. Select a file or directory and add a few ACEs to it
# 3. Use find -ls to check the "+" existen only with the selected file or
#    directory
# 4. Use find -acl to check only the selected file/directory in the list
#
