Having discussed this with Stuart and others at Linux Plumbers, I think that the binding is sufficient, and unlikely to change greatly unless there is a strong objection (Stuart, please correct me if I am wrong). Per Marc's comments there are probably some edge cases and/or wording details to sort out, but I think the common/simple case is sorted. I'll send a v2 once those have been settled. > If not, I will be sending out my patches for your consideration.
