From: Wang Weidong Date: Tue, 17 Dec 2013 12:30:17 +0000 Subject: [PATCH net-next] dccp: add check request_moduls in setup_jprobe Message-Id: <52B043D9.9090808@huawei.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: dccp@vger.kernel.org when register_jprobe failed, we will try request_module. But some time request_module will failed such as the dccp is not exist. so check the request_module for avoiding do register_jprobe again.
