Subject: [PATCH v6 08/12] KVM: introduce KVM_PFN_ERR_RO_FAULT
Date: Tue, 21 Aug 2012 11:01:19 +0800	[thread overview]
Message-ID: <5032F9FF.3000708@linux.vnet.ibm.com> (raw)
In-Reply-To: <5032F8FD.2020306@linux.vnet.ibm.com>

In the later patch, it indicates failure when we try to get a writable
pfn from the readonly memslot
