From mboxrd@z Thu Jan 1 00:00:00 1970 From: Cong Ding Subject: [PATCH] fs/cifs/cifs_dfs_ref.c: fix potential memory leakage Date: Tue, 22 Jan 2013 19:20:58 -0500 Message-ID: <1358900459-26277-1-git-send-email-dinggnu@gmail.com> Cc: Cong Ding To: Steve French , linux-cifs@vger.kernel.org, samba-technical@lists.samba.org, linux-kernel@vger.kernel.org Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-cifs.vger.kernel.org When it goes to error through line 144, the memory allocated to *devname is not freed, and the caller doesn't free it either in line 250. So we free the memroy of *devname in function cifs_compose_mount_options() when it goes to error.
