It would be less confusing to have the same interface as
_scratch_cycle_mount().

I'm not sure about these parts, but personally I think it's OK to just
skip atime related tests when you explicitly specify
MOUNT_OPTIONS=noatime. So, you state you want to test FS behavior with
noatime by specifying the MOUNT_OPTIONS, then it would be no use to
run those atime related tests anyway.

Or, we need to add _exclude_scratch_mount_option "strictatime" also?
