Subject: [PATCH 4/5] block: use bdev_get_queue() in blk-core.c
Date: Thu, 14 Oct 2021 15:03:29 +0100 [thread overview]
Message-ID: <efc41f880262517c8dc32f932f1b23112f21b255.1634219547.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1634219547.git.asml.silence@gmail.com>
Convert bdev->bd_disk->queue to bdev_get_queue(), it's uses a cached
queue pointer and so is fater.
