#
# DESCRIPTION:
# Verify that '/usr/bin/ls' command option supports ZFS ACL
#
# STRATEGY:
# 1. Create file and  directory in zfs filesystem
# 2. Verify that 'ls [-dv]' can list the ACEs of ACL of
#    file/directroy
# 3. Change the file/directory's acl
# 4. Verify that 'ls -l' can use the '+' to indicate the non-trivial
#    acl.
