Subject: [PATCH v8 12/13] block: call blk_account_io_start() in blk_execute_rq_nowait()
Date: Wed, 28 Aug 2019 15:54:28 -0600	[thread overview]
Message-ID: <20190828215429.4572-13-logang@deltatee.com> (raw)
In-Reply-To: <20190828215429.4572-1-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.
