Date: Thu, 2 Nov 2017 23:24:33 +0800 From: Ming Lei <ming.lei@...hat.com> To: Jens Axboe <axboe@...com>, linux-block@...r.kernel.org, Christoph Hellwig <hch@...radead.org> Cc: Omar Sandoval <osandov@...com>, Bart Van Assche <bart.vanassche@...disk.com>, Hannes Reinecke <hare@...e.com>, linux-kernel@...r.kernel.org, Ming Lei <ming.lei@...hat.com> Subject: [PATCH V3 2/7] blk-flush: don't run queue for requests of bypassing flush blk_insert_flush() should only insert request since run queue always follows it. In case of bypassing flush, we don't need to run queue because every blk_insert_flush() follows one run queue.
