Subject: [PATCH 1/7] accel/kvm: Let kvm_check_extension use global KVM state
Date: Tue, 23 Jun 2020 12:50:46 +0200	[thread overview]
Message-ID: <20200623105052.1700-2-philmd@redhat.com> (raw)
In-Reply-To: <20200623105052.1700-1-philmd@redhat.com>

As KVM supported extentions those should be the same for
all VMs, it is safe to directly use the global kvm_state
in kvm_check_extension().
