Just a heads-up that this will require some additional backporting love, since it breaks compilation of older md due to (I think) commit 8ae126660fddbe ("block: kill merge_bvec_fn() completely"). I tried to merge this into my 4.1++ (because SMR drama) but offhand didn't know how to fix the conflict in md, so maybe someone more familiar with the block layer/bio merging can help. -h
