This more or less lgtm to me but i have a couple of high-level points
1) It would be good to include performance improvement numbers, if you have them handy, from the reduced DMA of a the descriptor.
2) Somewhere in the comments, could you please explain what "privatization" of a descriptor is. I had to look at the runtime code to get an understanding of what privatization in teh context of a descriptor meant. I get how target_param is used, but it would have helped greatly to have an explanation for "privatization". Having said that, i see that the term is used pretty liberally throughout the PR so if this is documented somewehre, please include a link.
