This causes nfsd4_shutdown_callback to hang since  \ncl_cb_inflight is not 0. This hang lasts about 15 minutes until TCP  \nnotifies NFSD that the connection was dropped.  \n  \nThis patch modifies nfsd4_run_cb_work to skip the RPC call if  \nnfs4_client is in courtesy state. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"27 Feb 2025\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2025-02-27T06:11:23.000000Z"}]}
