From 105e0c441aa4797e0240d3652ce8e69c6b308cb6 Mon Sep 17 00:00:00 2001 From: Peng Hao <flyingpeng@tencent.com> Date: Tue, 22 Feb 2022 18:40:29 +0800 Subject: [PATCH] kvm: vmx: Fix typos comment in __loaded_vmcs_clear() Fix a comment documenting the memory barrier related to clearing a loaded_vmcs; loaded_vmcs tracks the host CPU the VMCS is loaded on via the field 'cpu', it doesn't have a 'vcpu' field.
