Subject: [PATCH v1 1/5] KVM: arm/arm64: Remove kvm_mmio_emulate tracepoint
Date: Wed, 12 Jun 2019 09:08:42 +0000 [thread overview]
Message-ID: <1560330526-15468-2-git-send-email-yuzenghui@huawei.com> (raw)
In-Reply-To: <1560330526-15468-1-git-send-email-yuzenghui@huawei.com>
In current KVM/ARM code, no one will invoke trace_kvm_mmio_emulate().
Remove this TRACE_EVENT definition.
