From fbc722aac1ce66960de50c0f488b6ff865a41d74 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Sat, 11 Feb 2023 00:35:34 +0000 Subject: [PATCH] KVM: VMX: Rename "KVM is using eVMCS" static key to match its wrapper Rename enable_evmcs to __kvm_is_using_evmcs to match its wrapper, and to avoid confusion with enabling eVMCS for nested virtualization, i.e. have "enable eVMCS" be reserved for "enable eVMCS support for L1". No functional change intended.
