Could you divide this *large* patch to several pieces ?
It looks you don't want to use functions based on zones, buddy-system, lru-list etc..
I think what you want is just a hierarchical memory allocator.
Why do you modify zone and make codes complicated ?
Can your memory allocater be implimented like mempool or hugetlb ?
They are not so invasive.
Bye,
