Subject: [PATCH 02/17] vmx: nest: rename host_vmcs
Date: Thu, 22 Apr 2010 17:41:14 +0800	[thread overview]
Message-ID: <1271929289-18572-3-git-send-email-qing.he@intel.com> (raw)
In-Reply-To: <1271929289-18572-1-git-send-email-qing.he@intel.com>

the VMCS region used for vmxon is named host_vmcs, which is
somewhat misleading in nested virtualization context, rename it
to vmxon_vmcs.
