4.15-stable review patch. If anyone has any objections, please let me know.

From: Jiufei Xue <jiufei....@linux.alibaba.com>
commit 7c5a0dcf557c6511a61e092ba887de28882fe857 upstream.
The vm counters is counted in sectors, so we should do the conversation
in submit_bio.
Fixes: 74d46992e0d9 ("block: replace bi_bdev with a gendisk pointer and
partitions index")
