Subject: [PATCH v13 09/13] dm-zone: use generic helpers to calculate offset from zone start
Date: Mon, 12 Sep 2022 10:22:00 +0200 [thread overview]
Message-ID: <20220912082204.51189-10-p.raghav@samsung.com> (raw)
In-Reply-To: <20220912082204.51189-1-p.raghav@samsung.com>
Use the bdev_offset_from_zone_start() helper function to calculate
the offset from zone start instead of using power of 2 based
calculation.
