Subject: [PATCH v7 13/14] block: call blk_account_io_start() in
 blk_execute_rq_nowait()
In-Reply-To: <20190801234514.7941-1-logang@deltatee.com>
References: <20190801234514.7941-1-logang@deltatee.com>
Message-ID: <20190801234514.7941-14-logang@deltatee.com>

All existing users of blk_execute_rq[_nowait]() are for passthrough
commands and will thus be rejected by blk_do_io_stat().

This allows passthrough requests to opt-in to IO accounting by setting
RQF_IO_STAT.
