Subject: [GIT PULL 42/45] lightnvm: do no update csecs and sos on 1.2
Date: Tue, 9 Oct 2018 13:12:12 +0200 [thread overview]
Message-ID: <20181009111215.7653-43-mb@lightnvm.io> (raw)
In-Reply-To: <20181009111215.7653-1-mb@lightnvm.io>
From: Javier González <javier@javigon.com>
1.2 devices exposes their data and metadata size through the separate
identify command. Make sure that the NVMe LBA format does not override
these values.
