From 554cf31474937f0a78045aaa7df565ffb6a29c43 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Tue, 6 Apr 2021 10:18:10 -0700 Subject: [PATCH] KVM: SVM: Add a comment to clarify what vcpu_svm.vmcb points at Add a comment above the declaration of vcpu_svm.vmcb to call out that it is simply a shorthand for current_vmcb->ptr. The myriad accesses to svm->vmcb are quite confusing without this crucial detail. No functional change intended.
