Miklos, Following the discussions on hugetlbfs-overlayfs, I wanted to see if we can do better to emulate the underlying file supported ops. Those patches don't actually help the hugetlbfs issue at all and I am not sure they improve anything, but I though it would be better if you had a look to say if there is anything interesting we can get from this. Thanks, Amir.
