36# DESCRIPTION:
37#
38# Setting a reservation on dataset should have no effect on any other
39# dataset at the same level in the hierarchy beyond using up available
40# space in the pool.
41#
42# STRATEGY:
43# 1) Create a filesystem
44# 2) Set a reservation on the filesystem
45# 3) Create another filesystem at the same level
46# 4) Set a reservation on the second filesystem
47# 5) Destroy both the filesystems
48# 6) Verify space accounted for correctly
