From 9e72fec62f315117e195b38c5c89b1cd53e9f703 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Thu, 27 Oct 2022 16:45:11 -0400 Subject: [PATCH] fs: dlm: fix sock release if listen fails commit 08ae0547e75ec3d062b6b6b9cf4830c730df68df upstream. This patch fixes a double sock_release() call when the listen() is called for the dlm lowcomms listen socket. The caller of dlm_listen_for_all should never care about releasing the socket if dlm_listen_for_all() fails, it's done now only once if listen() fails.
