36# DESCRIPTION:
37# When atime=on, verify the access time for files is updated when read. It
38# is available to fs and clone. To snapshot, it is unavailable.
39#
40# STRATEGY:
41# 1. Create pool and fs.
42# 2. Create '$TESTFILE' for fs.
43# 3. Create snapshot and clone.
44# 4. Setting atime=on on datasets except snapshot, and read '$TESTFILE'.
45# 5. Expect the access time is updated on datasets except snapshot.
