If users don't want to lose NUMA performance, just don't use it.

I agree with this, but it means that nobody will test any of your new code.

To get improved testing coverage, can you think of any temporary
testing-only patch which will cause testers to exercise the
memory-hotplug changes?

Hi Andrew,

OKïIâll think about it and post the testing patch. But I think a shell script
may be easier because the boot option is specified by user and the code only runs
when system is booting. So we need to reboot the system all the time.

Thanks. :)
