 advantages:
 
  * Before, iterating over bios was very awkward when you weren't processing
-   exactly one bvec at a time - for example, bio_copy_data() in fs/bio.c,
+   exactly one bvec at a time - for example, bio_copy_data() in block/bio.c,
    which copies the contents of one bio into another. Because the biovecs
    wouldn't necessarily be the same size, the old code was tricky convoluted -
    it had to walk two different bios at the same time, keeping both bi_idx and
