The Redhat 6 release notes mentions that "Extended Page Table age bits enables a host to make smarter choices for swapping memory under memory pressure". I couldn't find any related patches on the LKML that use this accessed bit to swap out the inactive VM pages. I was wondering if this feature is available in rhel or any other non-enterprise versions.
