Subject:    [PATCH 02/17] target/core: Use the SECTOR_SHIFT constant
From:       Bart Van Assche <bvanassche () acm ! org>
Date:       2018-09-17 21:35:39
Message-ID: 20180917213554.987-3-bvanassche () acm ! org
[Download RAW message or body]

Instead of duplicating the SECTOR_SHIFT definition from <linux/blkdev.h>,
use it. This patch does not change any functionality.
