Hi Greg, I find this system hang issue at v4.0, and it should exist at v3.19 too. Do you mean Ying forget to add tag "Cc: sta...@vger.kernel.org # 3.19" at commit log or you think this fix is too large? -- Best Regards, Peter Chen -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
