Many block drivers accounting io stat based on bio (e.g. NVMe...), the blk_account_io_start/end() which is based on request does not make sense to them, so here we introduce the similar help function named generic_start/end_io_acct base on raw sectors, and it can simplify some driver's open io accounting code.Gu Zheng (6): blk: introduce generic io stat accounting help function NVMe: use generic io stat accounting functions to simplify nvme_start/end_io_acct md/bcache: use generic io stats accounting functions to simplify io stat accounting drbd: use generic io stats accounting functions to simplify io stat accounting md: use generic io stats accounting functions to simplify io stat accounting block/rsxx: use generic io stats accounting functions to simplify io stat accounting
Thanks, this looks good. I'll apply it, except 2/6, since nvme no longer uses them.
