Ping.. Thinking about a repost, as this series shouldn't be able to apply after we've got more relevant patches into -mm. E.g., the full minor fault, and also some small stuff like pagemap, as we need one more patch to support shmem/hugetlbfs too. Hugh, haven't received any further comment from you on shmem side (or on the general idea). It would be great to still have some of your input. Let me know if you prefer to read a fresh new version otherwise. Thanks! -- Peter Xu
