The\ncallers of do_inject_vcpu() are modified to pass the pointer to the\nbool flag; whenever a Store Status operation is needed, the callers can\nnow perform it outside the spinlock.\n\nOpportunistically refactor kvm_s390_set_irq_state() to use\nscoped_guard() and __free().\n\n[ Added Fixes tag while picking -- Claudio ]"
