Subject: [PATCH 01/20] lightnvm: re-convert ppa format on I/O failure
Date: Mon, 26 Jun 2017 11:57:10 +0200 [thread overview]
Message-ID: <1498471049-25505-2-git-send-email-javier@cnexlabs.com> (raw)
In-Reply-To: <1498471049-25505-1-git-send-email-javier@cnexlabs.com>
In case of a failure when submitting a request, convert the ppa_list

recovery
