Subject: [PATCH 02/20] lightnvm: propagate right error code to target
Date: Mon, 26 Jun 2017 11:57:11 +0200 [thread overview]
Message-ID: <1498471049-25505-3-git-send-email-javier@cnexlabs.com> (raw)
In-Reply-To: <1498471049-25505-1-git-send-email-javier@cnexlabs.com>
If nvme_alloc_request fails, propagate the right error, instead of
assuming ENOMEM.
