Date: Sat, 14 Nov 2015 11:21:06 +0800 From: Yaowei Bai <baiyaowei@...s.chinamobile.com> To: gleb@...nel.org, pbonzini@...hat.com Cc: kvm@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 1/2] KVM: kvm_is_visible_gfn can be boolean This patch makes kvm_is_visible_gfn return bool due to this particular function only using either one or zero as its return value.
