Oh, I replied the personal mail.

Thanks for your explaination. I don't know this complex situation before.

I think the quota module is belong to kernel-default package but not 
belong to kernel-default-base package. So jeos use kernel-default-base 
will pass kernel config check but indeed it miss this module.

This problem also occurs on centos if we use module from 
kernel-module-extra.

So a better solution is that if the module is belong to 
kernel-default-base ,then we can use kconfig check, but if the module is 
not belong to kernel-default-base, then use need_driver maybe more correct.
