Subject: [dpdk-stable] [PATCH] net/ice: check process type in close operation
Date: Fri, 5 Mar 2021 17:25:09 +0800 [thread overview]
Message-ID: <20210305092509.121938-1-dapengx.yu@intel.com> (raw)
From: Dapeng Yu <dapengx.yu@intel.com>
The secondary processes are not allowed to release shared resources.
Only process-private resources should be freed in a secondary process.
So the close operation is just forbidden in a secondary process.
Fixes: bd513ece3c40 ("net/ice: release port upon close")
