Subject: [PATCH for-rc or next 2/3] IB/hfi1: Do not destroy link_wq when the device is shut down
Date: Mon, 11 May 2020 23:13:22 -0400 [thread overview]
Message-ID: <20200512031322.189865.4129.stgit@awfm-01.aw.intel.com> (raw)
In-Reply-To: <20200512030622.189865.65024.stgit@awfm-01.aw.intel.com>
From: Kaike Wan <kaike.wan@intel.com>
The workqueue link_wq should only be destroyed when the hfi1 driver
is unloaded, not when the device is shut down.
Fixes: 71d47008ca1b ("IB/hfi1: Create workqueue for link events")
