Subject: [PATCH 7/9] KVM: x86: Rename SMM tracepoint to make it reflect reality
Date: Wed, 9 Jun 2021 11:56:17 -0700 [thread overview]
Message-ID: <20210609185619.992058-8-seanjc@google.com> (raw)
In-Reply-To: <20210609185619.992058-1-seanjc@google.com>
Rename the SMM tracepoint, which handles both entering and exiting SMM,
from kvm_enter_smm to kvm_smm_transition.
