Subject: [PATCH 09/11] net/txgbe: check process type in close operation
Date: Thu, 28 Sep 2023 17:47:56 +0800 [thread overview]
Message-ID: <20230928094758.1076236-10-jiawenwu@trustnetic.com> (raw)
In-Reply-To: <20230928094758.1076236-1-jiawenwu@trustnetic.com>
The secondary processes are not allowed to release shared resources.
Only process-private resources should be freed in a secondary process.
Most of the time, there is no process-private resource,
so the close operation is just forbidden in a secondary process.
Fixes: e1698e383c2a ("net/txgbe: add device init and uninit")
