Since test uses 160 multiple for malloc size, we should also use 160 multiple
for total variable instead of 16, then comparison is meaningful. So fix it.

Also change the ">" to ">=" so that the test is technically valid.

Yang,

Thank you very much for your great work with this patch.

I need your help in order to complete the FSF copyright assignment process
with Fujitsu.

I've sent you an Naohiro and email to start the process.

Thank you for your help.
