[PATCH V2 0/4] fix a few problems in block layer

[Jiufei Xue <jiufei.xue@xxxxxxxxxxxxxxxxx>]

I have found a few problems while reviewing the patch 74d46992e0d9
("block: replace bi_bdev with a gendisk pointer and partitions index"),
So fix them.

Changes since v1:
- add a Fixes tag in individual patch.
- check end-of-device of bio in blk_partition_remap when the bi_partno
is not zero to avoid another partition lookup.

  block: fix the count of PGPGOUT for WRITE_SAME
  block: bio_check_eod() needs to consider partition
  block: display the correct disk name for bio
  block: fix a typo and modify the documentation for bio
