Subject: [PATCH v2 06/16] lightnvm: pblk: recover only written metadata
Date: Fri, 22 Mar 2019 15:48:33 +0100	[thread overview]
Message-ID: <20190322144843.9602-7-igor.j.konopko@intel.com> (raw)
In-Reply-To: <20190322144843.9602-1-igor.j.konopko@intel.com>

This patch ensures that smeta was fully written before even
trying to read it based on chunk table state and write pointer.
