From 19821fee3ed42e5b294e95814892d0ad6a9890c9 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 17 May 2023 10:42:23 -0700 Subject: block: Introduce blk_rq_is_seq_zoned_write() Introduce the function blk_rq_is_seq_zoned_write(). This function will be used in later patches to preserve the order of zoned writes that require write serialization. This patch includes an optimization: instead of using rq->q->disk->part0->bd_queue to check whether or not the queue is associated with a zoned block device, use rq->q->disk->queue.
