Subject: [PATCH] KVM: get rid of var page in kvm_set_pfn_dirty()
Date: Thu, 5 Dec 2019 11:05:05 +0800
Message-ID: <1575515105-19426-1-git-send-email-linmiaohe@huawei.com> (raw)

From: Miaohe Lin <linmiaohe@huawei.com>

We can get rid of unnecessary var page in
kvm_set_pfn_dirty() , thus make code style
similar with kvm_set_pfn_accessed().
