#
# DESCRIPTION:
#	Verify chmod permission settings on files and directories, as both root
#	and non-root users.
#
# STRATEGY:
#	1. Loop root and $ZFS_ACL_STAFF1 as root and non-root users.
#	2. Create test file and directory in zfs filesystem.
#	3. Execute 'chmod' with specified options.
#	4. Check 'ls -l' output and compare with expect results.
#
# NOTE:
#	The test does not work for default "discard" aclmode property.
#	The test is modified to run with "passthrough" aclmode property.
