Sorry for re-sending this e-mail. But the e-mail address of mine has been 
changed. And I haven’t seen this e-mail in several kernel mail list 
archives after a night of sleep. I’m wondering if the e-mail is sent
correctly. So I finally decide to re-send this e-mail. Again, I feel
sorry for sending the same thing for two times.

BTW, how can i judge if my e-mail is correctly sent to the mail list?
