A couple of things... There's a massive and complex reject storm against Kirill's page-flags and thp changes. The problems in hugetlb.c are more than I can reasonably fix up, sorry. How would you feel about redoing the patches against next -mm? Secondly, "mm: introduce lazyfree LRU list" and "mm: support MADV_FREE on swapless system" are new, and require significant reviewer attention. But there's so much other stuff flying around that I doubt if we'll get effective review. So perhaps it would be best to shelve those new things and introduce them later, after the basic old MADV_FREE work has settled in? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
