I'm going to need a very similar iterator API, except it shouldn't go through an ib_umem object. Instead, a scatterlist would be given explicitly as a parameter. Do you think there's a way to make this code more generic and then use it for umem as a specific use case? I'll be glad to help with any changes needed. Thanks, Gal
