Subject: [dpdk-stable] [PATCH] vdev: fix rte_mp_request_sync() memleak on scan
Date: Thu, 25 Oct 2018 12:47:35 +0200 [thread overview]
Message-ID: <20181025104735.137381-1-dariusz.stojaczyk@intel.com> (raw)
rte_mp_request_sync() says that the caller is responsible
for freeing one of its parameters afterwards. vdev didn't
do that, causing a memory leak.
Fixes: cdb068f031c6 ("bus/vdev: scan by multi-process channel")
