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. Signed-off-by: Sean Christopherson <seanjc@google.com> --- arch/x86/kvm/svm/svm.h | 1 + 1 file changed, 1 insertion(+)
