Subject: [PATCH v4 5/6] KVM: x86: use the fast way to invalid all pages
Date: Sat, 27 Apr 2013 11:13:21 +0800	[thread overview]
Message-ID: <1367032402-13729-6-git-send-email-xiaoguangrong@linux.vnet.ibm.com> (raw)
In-Reply-To: <1367032402-13729-1-git-send-email-xiaoguangrong@linux.vnet.ibm.com>

Replace kvm_mmu_zap_all by kvm_mmu_invalid_all_pages except on
the path of mmu_notifier->release() which will be fixed in
the later patch
