I was not aware there's a long story for this issue. I hit this issue a lot of times during stress test and root caused it. After applying my patch, I did extensive test on 5 machines for a long time, it does not reproduced anymore so I submitted the patch. I will do more research on this issue. -- 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/
