    bio_vec-backed iov_iter · 62a8067a

    New variant of iov_iter - ITER_BVEC in iter->type, backed with
    bio_vec array instead of iovec one.  Primitives taught to deal
    with such beasts, __swap_write() switched to using that kind
    of iov_iter.
    
    Note that bio_vec is just a <page, offset, length> triple - there's
    nothing block-specific about it.  I've left the definition where it
    was, but took it from under ifdef CONFIG_BLOCK.
    
    Next target: ->splice_write()...
