Subject: [PATCH v15 10/13] dm-table: allow zoned devices with non power-of-2 zone sizes
Date: Fri, 23 Sep 2022 19:36:15 +0200 [thread overview]
Message-ID: <20220923173618.6899-11-p.raghav@samsung.com> (raw)
In-Reply-To: <20220923173618.6899-1-p.raghav@samsung.com>
Allow dm to support zoned devices with non power-of-2(po2) zone sizes as
the block layer now supports it.
