Hello All: I have to leave Sunrus, the mail address (gang.c...@sunrus.com.cn) will be closed soon (Sunrus will be closed soon because of money, I guess).
I change my new email address (xili_gchen_5...@hotmail.com) to continue communicating. gang.chen.5...@gmail.com is still have effect, but it is not stable (gmail in China is not stable). And if the patches can pass checking, please add me as the maintainer, and let Andreas, Chris, Richard, and Peter as Reviewed-by. Thanks.
