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 Signed-off-by: Avi Kivity --- diff --git a/virt/kvm/async_pf.c b/virt/kvm/async_pf.c index 74268b4c2ee1..ebae24b62c90 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); } }
