If you're saying that http://ozlabs.org/~akpm/mmots/broken-out/mm-mempolicy-skip-non-migratable-vmas-when-setting-mpol_mf_lazy.patch and http://ozlabs.org/~akpm/mmots/broken-out/mm-hugetlbfs-unmap-pages-if-page-fault-raced-with-hole-punch.patch are the final everything-works versions then we're all good to go now. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
