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!
