A inode is necessary for some drivers that needs special address_space
and address_space_operation for page migration. Each drivers can create
inode with the anon_inodefs.

Add framework to register callback functions and

There are some modes of page isolation so that isolate interface

Finally calling migration of balloon driver is re

My platform is suffering with the external fragmentation problem.
If I run a heavy load test for a few days in 1GB memory system, I cannot

I'm sorry.
But if mm developers agree with this approach, I will complete this patch.
I would do appreciate any feedback.
