Subject: [PATCH v8 5/8] kvm: Rename make_all_cpus_request() to kvm_make_all_cpus_request() and make it non-static.
Date: Wed, 24 Sep 2014 15:57:55 +0800 [thread overview]
Message-ID: <1411545478-9848-6-git-send-email-tangchen@cn.fujitsu.com> (raw)
In-Reply-To: <1411545478-9848-1-git-send-email-tangchen@cn.fujitsu.com>
Since different architectures need different handling, we will add some arch specific
code later. The code may need to make cpu requests outside kvm_main.c, so make it
non-static and rename it to kvm_make_all_cpus_request().
