From cdc238eb72f6b94b6c33b98c07b9fc3ac5e57b18 Mon Sep 17 00:00:00 2001 From: Yi Wang Date: Wed, 10 Jul 2019 08:24:03 +0800 Subject: kvm: x86: Fix -Wmissing-prototypes warnings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We get a warning when build kernel W=1: arch/x86/kvm/../../../virt/kvm/eventfd.c:48:1: warning: no previous prototype for ‘kvm_arch_irqfd_allowed’ [-Wmissing-prototypes] kvm_arch_irqfd_allowed(struct kvm *kvm, struct kvm_irqfd *args) ^ The reason is kvm_arch_irqfd_allowed() is declared in arch/x86/kvm/irq.h, which is not included by eventfd.c. Considering kvm_arch_irqfd_allowed() is a weakly defined function in eventfd.c, remove the declaration to kvm_host.h can fix this.
