35# DESCRIPTION:
36#	'zfs recv -F' to force rollback.
37#
38# STRATEGY:
39#	1. Create pool and fs.
40#	2. Create some files in fs and take a snapshot1.
41#	3. Create another files in fs and take snapshot2.
42#	4. Create incremental stream from snapshot1 to snapshot2.
43#	5. fs rollback to snapshot1 and modify fs.
44#	6. Verify 'zfs recv -F' can force rollback.
