Subject: [PATCH v2 2/5] padata: remove reorder_objects
Date: Wed, 28 Aug 2019 18:14:22 -0400	[thread overview]
Message-ID: <20190828221425.22701-3-daniel.m.jordan@oracle.com> (raw)
In-Reply-To: <20190828221425.22701-1-daniel.m.jordan@oracle.com>

reorder_objects is unused since the rework of padata's flushing, so
remove it.
