From 8abaae8d85d4e1de0fcc81b733ba04a5d318ba7a Mon Sep 17 00:00:00 2001 From: Younger Liu Date: Tue, 12 Nov 2013 15:07:04 -0800 Subject: [PATCH] ocfs2: do not call brelse() if group_bh is not initialized in ocfs2_group_add() If group_bh is not initialized, there is no need to release. This problem does not cause anything wrong, but the patch would make the code more logical.
