Subject[PATCH AUTOSEL 4.19 124/167] scsi: target/core: Use the SECTOR_SHIFT constant
Date
From: Bart Van Assche <bvanassche@acm.org>

[ Upstream commit 80b045b385cfef10939c913fbfeb19ce5491c1f2 ]

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