Hello Jens,

All are bioset / bvec improvement, and most of them are quite
straightforward.

V3:
- share two line code via goto with one label, only patch 1 is
changed

V2:
- patch style change, most is in patch 1
- commit log change

Ming Lei (6):
block: manage bio slab cache by xarray
block: don't pass BIOSET_NEED_BVECS for q->bio_split
block: don't allocate inline bvecs if this bioset needn't bvecs
block: set .bi_max_vecs as actual allocated vector number
block: move three bvec helpers declaration into private helper
bcache: don't pass BIOSET_NEED_BVECS for the 'bio_set' embedded in
'cache_set'
