I have done some investigation on it and it is being triggered by a bug in the private reservation tracking patches. It is triggered by the hugetlb test which causes some complex vma splits to occur on a private mapping. I believe I have the underlying problem nailed and do have some nearly complete patches for this and they should be in a postable state by tommorrow. -apw -- To unsubscribe from this list: send the line "unsubscribe kernel-testers" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
