Subject: [PATCH v2 07/14] KVM: SVM: Append "_enabled" to module-scoped SEV/SEV-ES control variables
Date: Wed, 13 Jan 2021 16:37:01 -0800	[thread overview]
Message-ID: <20210114003708.3798992-8-seanjc@google.com> (raw)
In-Reply-To: <20210114003708.3798992-1-seanjc@google.com>

Rename sev and sev_es to sev_enabled and sev_es_enabled respectively to
better align with other KVM terminology, and to avoid pseudo-shadowing
when the variables are moved to sev.c in a future patch ('sev' is often
used for local struct kvm_sev_info pointers.

No functional change intended.
