Subject: [PATCH 03/27] target: fix discard alignment on partitions
Date: Fri, 15 Apr 2022 06:52:34 +0200 [thread overview]
Message-ID: <20220415045258.199825-4-hch@lst.de> (raw)
In-Reply-To: <20220415045258.199825-1-hch@lst.de>
Use the proper bdev_discard_alignment helper that accounts for partition
offsets.
Fixes: c66ac9db8d4a ("[SCSI] target: Add LIO target core v4.0.0-rc6")
