synxtax for mounting ext3 with defaults and noatime?

[Anand Buddhdev <arb anand org>]

My OS is RedHat linux 7.3. I have read the mount manpage, but I'm unclear
about one thing:

If I mount an ext3 filesystem with the 'defaults' option, I get
rw,suid,dev,exec,auto,nouser,async.

Now, I want to mount it with the noatime option. Do I remove the
word 'defaults' and replace it with 'noatime', or do I set it to
'defaults,noatime'.

In my understanding, if I remove 'defaults' and replace it with 'noatime',
then that's the only option I get. However, if I enter 'defaults,noatime',
then which option does the FS get mounted with?

Thanks for your help.
