The original concern was that dax-reflink could not be implemented without ABI regressions. As far as I can see that concern has been put to rest by the proposed patches. Am I wrong? So, if we're committed to not breaking past promises I think this change can be made out-of-order from when the reflink support patches land. Acked-by: Dan Williams ...but I'm also fine with waiting for the final reflink merge.
