Acked-by: Lianbo Jiang <lijiang(a)redhat.com&gt; Thanks, but sorry, I've changed my mind.. For safety, I would like to keep the ping check, and I will give up the automated "git clone" in the specific environment. I found that I can build it by manual "git clone" and "make extensions". Could you check the following patch again?
