Subject: [PATCH v3 0/2] Optimize r1conf->r1bio_pool

The r1conf->r1bio_pool field was previously a struct, 
which caused a bug after raid1_reshape.
These patch changes it to a pointer type 
and removes struct pool_info and related code.

Wang Jinchao (2):
  md/raid1: change r1conf->r1bio_pool to a pointer type
  md/raid1: remove struct pool_info and related code

v1: Replace mempool_init() with mempool_create()
v2: Replace mempool_init() with mempool_create_kmalloc_pool()
v3: Fix checkpatch errors and a bug in calculating new_r1bio_size

The idea was proposed by Kuai, and I implemented it.
Thanks for the guidance and review.
