Subject: [PATCH v4 2/6] KVM: x86: Move declaration of kvm_cpu_dirty_log_size() to kvm_dirty_ring.h
Date: Tue, 27 Sep 2022 08:54:35 +0800 [thread overview]
Message-ID: <20220927005439.21130-3-gshan@redhat.com> (raw)
In-Reply-To: <20220927005439.21130-1-gshan@redhat.com>
Not all architectures like ARM64 need to override the function. Move
its declaration to kvm_dirty_ring.h to avoid the following compiling
warning on ARM64 when the feature is enabled.
arch/arm64/kvm/../../../virt/kvm/dirty_ring.c:14:12: \
warning: no previous prototype for 'kvm_cpu_dirty_log_size' \
[-Wmissing-prototypes] \
int __weak kvm_cpu_dirty_log_size(void)
Reported-by: kernel test robot <lkp@intel.com>
