35# DESCRIPTION:
36# When relatime=on, verify the access time for files is updated when first
37# read but not on second.
38# It 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 and relatime=on on datasets.
45# 5. Expect the access time is updated for first read but not on second.
