From 038851e38586ded536dca8349dc8457c0d21f674 Mon Sep 17 00:00:00 2001 From: Gleb Natapov Date: Mon, 3 Aug 2009 14:57:51 -0300 Subject: [PATCH] KVM: MMU: do not free active mmu pages in free_mmu_pages() (cherry picked from commit f00be0cae4e6ad0a8c7be381c6d9be3586800b3e) free_mmu_pages() should only undo what alloc_mmu_pages() does. Free mmu pages from the generic VM destruction function, kvm_destroy_vm().
