Message-ID: <5010C059.50007@linux.vnet.ibm.com> Date: Thu, 26 Jul 2012 11:58:17 +0800 From: Xiao Guangrong <xiaoguangrong@...ux.vnet.ibm.com> To: Xiao Guangrong <xiaoguangrong@...ux.vnet.ibm.com> CC: Avi Kivity <avi@...hat.com>, Marcelo Tosatti <mtosatti@...hat.com>, LKML <linux-kernel@...r.kernel.org>, KVM <kvm@...r.kernel.org> Subject: [PATCH v2 2/3] KVM: use kvm_release_page_clean to release the page In kvm_async_pf_wakeup_all, it uses bad_page to generate broadcast wakeup, and uses put_page to release bad_page, the work depends on the fact that bad_page is the normal page. But we will use the error code instead of bad_page, so use kvm_release_page_clean to release the page which will release the error code properly Signed-off-by: Xiao Guangrong <xiaoguangrong@...ux.vnet.ibm.com> --- virt/kvm/async_pf.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/virt/kvm/async_pf.c b/virt/kvm/async_pf.c index 74268b4..ebae24b 100644 --- a/virt/kvm/async_pf.c +++ b/virt/kvm/async_pf.c @@ -112,7 +112,7 @@ void kvm_clear_async_pf_completion_queue(struct kvm_vcpu *vcpu) typeof(*work), link); list_del(&work->link); if (work->page) - put_page(work->page); + kvm_release_page_clean(work->page); kmem_cache_free(async_pf_cache, work); } spin_unlock(&vcpu->async_pf.lock); @@ -139,7 +139,7 @@ void kvm_check_async_pf_completion(struct kvm_vcpu *vcpu) list_del(&work->queue); vcpu->async_pf.queued--; if (work->page) - put_page(work->page); + kvm_release_page_clean(work->page); kmem_cache_free(async_pf_cache, work); } } -- 1.7.7.6 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
