Subject: [PATCH 5/7] KVM: x86: Add macro wrapper for defining kvm_exit tracepoint
Date: Fri, 17 Jul 2020 23:38:52 -0700 [thread overview]
Message-ID: <20200718063854.16017-6-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200718063854.16017-1-sean.j.christopherson@intel.com>
Macrofy the definition of kvm_exit so that the definition can be reused
verbatim by kvm_nested_vmexit.
No functional change intended.
