Dear joonsoo kim,

Hello,

I stopped to implement it, because there are other bugs on CMA related codes.
Although aggressively allocate... doesn't have bugs itself, it enlarges
existing freepage counting bugs significantly so I'm first trying to fix
those bugs. See the below link.

I will restart to implement aggressively... after fixing these bugs.

If you have interest on next version of aggressively allocate..., see the
following link.

Thanks.
