Subject: [PATCH] SUNRPC: task should be exit if encode return EKEYEXPIRED more times
Date: Mon, 29 Apr 2019 17:32:31 +0800 [thread overview]
Message-ID: <1556530351-81780-1-git-send-email-zhangxiaoxu5@huawei.com> (raw)
If the rpc.gssd always return cred success, but now the cred is
expired, then the task will loop in call_refresh and call_transmit.
Exit the rpc task after retry.
