From f1d7231cede93a42d75b6d3c5ca599e94a273e89 Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Thu, 25 Jan 2018 18:32:29 +0100 Subject: KVM: arm/arm64: Fix userspace_irqchip_in_use counting We were not decrementing the static key count in the right location. kvm_arch_vcpu_destroy() is only called to clean up after a failed VCPU create attempt, whereas kvm_arch_vcpu_free() is called on teardown of the VM as well. Move the static key decrement call to kvm_arch_vcpu_free().
