    block: Convert bio_iovec() to bvec_iter · a4ad39b1
    Kent Overstreet authored
    For immutable biovecs, we'll be introducing a new bio_iovec() that uses
    our new bvec iterator to construct a biovec, taking into account
    bvec_iter->bi_bvec_done - this patch updates existing users for the new
    usage.
    
    Some of the existing users really do need a pointer into the bvec array
    - those uses are all going to be removed, but we'll need the
    functionality from immutable to remove them - so for now rename the
    existing bio_iovec() -> __bio_iovec(), and it'll be removed in a couple
    patches.
