Subject: [PATCH 9/9] padata: remove cpu_index from the parallel_queue
Date: Mon, 12 Aug 2019 20:52:24 -0400
Message-ID: <20190813005224.30779-10-daniel.m.jordan@oracle.com> (raw)
In-Reply-To: <20190813005224.30779-1-daniel.m.jordan@oracle.com>

With the removal of the ENODATA case from padata_get_next, the cpu_index
field is no longer useful, so it can go away.
