## Overview

In the Linux kernel, the following vulnerability has been resolved:

KVM: s390: Add missing srcu in kvm_s390_set_irq_state()

Like kvm_s390_inject_vcpu(), kvm_s390_set_irq_state() also needs the
kvm->srcu or the slots lock when performing the Store status operation.

Fix by taking kvm->srcu in kvm_s390_set_irq_state().
