[PATCH v4 00/12] Block cleanups

[Kent Overstreet]

CHANGES SINCE LAST VERSION:

Split off the "make generic_make_request() handle arbitrary size bios" - this
patch series now just kills bi_destructor and reworks bio splitting.

Split out the "rework bio splitting" patch based on Boaz's feedback - now I've
got one patch that introduces the new bio_split() and another that rewrites
bio_pair_split(), which makes the patches much more readable.

Going to try and finish off the rest of the patches that get rid of
merge_bvec_fn, but that'll be a separate patch series.

Kent Overstreet (12):
  block: Generalized bio pool freeing
  dm: Use bioset's front_pad for dm_rq_clone_bio_info
  block: Add bio_reset()
  pktcdvd: Switch to bio_kmalloc()
  block: Kill bi_destructor
  block: Add an explicit bio flag for bios that own their bvec
  block: Rename bio_split() -> bio_pair_split()
  block: Introduce new bio_split()
  block: Rework bio_pair_split()
  block: Add bio_clone_kmalloc()
  block: Add bio_clone_bioset()
  block: Only clone bio vecs that are in use
