As promised earlier [1], here are the patches which I would like to merge into 5.11 to support THPs. They depend on that earlier series. If there's anything in here that you'd like to see pulled out and added to that earlier series, let me know. There are a couple of pieces in here which aren't exactly part of iomap, but I think make sense to take through the iomap tree.
