Subject: [PATCH 0/6] block: improvement on bioset & bvec allocation

Hello,

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


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'
