Yes, I think you are right~! I don't want this utility can't be run
without a properly configured kernel and this full-scan method will
be used again when we dumping with an image file.
But I'm worry about the performance. As we dump one specified peb
now, we can't record the mapping table and need to do full scan
each time running this utility.
Anyway, I will try what you said first~!
Thanks~!
