Subject: Page Replacement Algo Enhancement to Flush lest recently used memory page

I'm looking for right kernel API to be able to flush the least
recently used memory page from inactive memory.

I want to develop a kernel module such that it will free least
recently used memory every n seconds untill inactive memory is 0.

This is to reduce the memory allocated to a linux VM dynamically and
make it available to other vms of the host or hypervisor itself.
