Looks nice. I wonder whether this could be extended to create a "streaming" dma-buf from a user space mapping. That could be used as a generic way to implement streaming (user) buffer objects, rather than to add explicit support for those in, for example, TTM.
I'm somewhat reluctant to beef this up needlessly to prevent it from being used for purposes other than testing.
