Subject: [PATCH 01/16] vmx: nest: rename host_vmcs
Date: Wed,  8 Sep 2010 23:22:09 +0800	[thread overview]
Message-ID: <1283959344-3837-2-git-send-email-qing.he@intel.com> (raw)
In-Reply-To: <1283959344-3837-1-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.
