And I notice there is a similar post here: https://lkml.org/lkml/2013/8/17/27 And it has been fixed by mainline(by Commit a0c516cbfc74),and there is some other patches to optimize the patch(Commit f614a9f48ded). I just want to know is there any plan to back port the patchs to 3.10.y? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
