From f51234c2cd3ab8bed836e09686e27877e1b55f2a Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Fri, 5 Jan 2007 16:36:52 -0800 Subject: [PATCH] KVM: MMU: Free pages on kvm destruction Because mmu pages have attached rmap and parent pte chain structures, we need to zap them before freeing so the attached structures are freed.
