Date: Thu, 6 Oct 2022 04:59:18 -0400 From: yanjun.zhu@...ux.dev To: jgg@...pe.ca, leon@...nel.org, zyjzyj2000@...il.com, linux-rdma@...r.kernel.org, yanjun.zhu@...ux.dev, netdev@...r.kernel.org, davem@...emloft.net Subject: [PATCHv2 3/6] RDMA/nldev: Add dellink function pointer From: Zhu Yanjun <yanjun.zhu@...ux.dev> The newlink function pointer is added. And the sock listening on port 4791 is added in the newlink function. So the dellink function is needed to remove the sock.
