    dm: Refactor for new bio cloning/splitting · 1c3b13e6
    Kent Overstreet authored
    We need to convert the dm code to the new bvec_iter primitives which
    respect bi_bvec_done; they also allow us to drastically simplify dm's
    bio splitting code.
    Also, it's no longer necessary to save/restore the bvec array anymore -
    driver conversions for immutable bvecs are done, so drivers should never
    be modifying it.
    Also kill bio_sector_offset(), dm was the only user and it doesn't make
    much sense anymore.
