Hi, Vinod and All, I found, somtimes, I cannot received some mails from this mailing list. For example, I sent my v2 series on 7th, Jan, https://patchwork.kernel.org/project/linux-dmaengine/list/?series=62713 It appeared on patchwork.kernel.org but I haven't received it in this mailing list. And I found randomly, a month or two months, I am unsubscribed from this list automatically. Then I have to re-subscribe the list. Have someone met similar problem as me? Or maybe I missed some necessary settings? Shunyong. Thanks.
