From 6692cef30b7caf7525ae99670cddbaf28f1f9d40 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Wed, 26 Nov 2008 14:51:08 +0100 Subject: [PATCH] KVM: s390: Fix memory leak of vcpu->run The s390 backend of kvm never calls kvm_vcpu_uninit. This causes a memory leak of vcpu->run pages. Lets call kvm_vcpu_uninit in kvm_arch_vcpu_destroy to free the vcpu->run.
