I suspect the whole series could use some reordering.
patch 1:
add ->bio_split and blk_queue_split
patch 2..n:
one for each non-trivial driver that implements ->merge_bvec_fn to remove it and instead split bios in ->make_request. The md patch to do the right thing in chunk_aligned_read goes into the general md patch here. The bcache patch also goes into this series.
patch n+1:
- add blk_queue_split calls for remaining trivial drivers
patch n+2:
- remove ->merge_bvec_fn and checking of max_sectors a for all drivers, simplify bio_add_page
patch n+2:
- remove splitting in blkdev_issue_discard
patch n+3
- remove bio_fits_rdev
patch n+4
- remove bio_get_nr_vecs
patch n+4
- use bio_add_page
patch n+5
- update documentation
