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,
OK，I‘ll 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. :)
