Subject: [PATCH 2/8] KVM: SEV-ES: rename guest_ins_data to sev_pio_data
Date: Wed, 13 Oct 2021 12:56:10 -0400 [thread overview]
Message-ID: <20211013165616.19846-3-pbonzini@redhat.com> (raw)
In-Reply-To: <20211013165616.19846-1-pbonzini@redhat.com>
Since we will be using this for OUTS emulation as well, change the name to
something that refers to any kind of PIO. Also spell out what it is used
for, namely SEV-ES.
No functional change intended.
Cc: stable@vger.kernel.org
Fixes: 7ed9abfe8e9f ("KVM: SVM: Support string IO operations for an SEV-ES guest")
