Subject: [PATCH v5 2/7] KVM: x86: Move declaration of kvm_cpu_dirty_log_size() to kvm_dirty_ring.h
Date: Wed,  5 Oct 2022 08:41:49 +0800	[thread overview]
Message-ID: <20221005004154.83502-3-gshan@redhat.com> (raw)
In-Reply-To: <20221005004154.83502-1-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)
