Subject: [dpdk-dev] [PATCH v2] raw/ioat: fix parameter shadow warning
Date: Mon, 10 May 2021 12:55:14 +0000	[thread overview]
Message-ID: <20210510125514.12914-1-kevin.laatz@intel.com> (raw)
In-Reply-To: <20210507172025.181720-1-kevin.laatz@intel.com>

In the function __idxd_completed_ops() we have a parameter shadow warning
due to a local variable having the same name as one of the function
parameters. This issue is fixed by simply renaming the local variable.

This warning was discovered during an OVS build with DPDK 21.05-rc2. The
OVS build passes the -Wshadow flag by default, allowing the warning to be
seen.

Fixes: 245efe544d8e ("raw/ioat: report status of completed jobs")
