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, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ .
