Subject: [dpdk-dev] [PATCH 2/4] raw/ioat: include extra info in error messages
Date: Fri, 21 Aug 2020 16:59:43 +0100
Message-ID: <20200821155945.29415-3-bruce.richardson@intel.com> (raw)
In-Reply-To: <20200821155945.29415-1-bruce.richardson@intel.com>

In case of any failures, include the function name and the line number of
the error message in the message, to make tracking down the failure easier.
