From 4373519db4dbca05341a60b28f6e159b106e4c4b Mon Sep 17 00:00:00 2001 From: Jan Schmidt Date: Tue, 28 May 2013 15:47:22 +0000 Subject: [PATCH] Btrfs: fix memory patcher through fs_info->qgroup_ulist Commit 5b7c665e introduced fs_info->qgroup_ulist, that is allocated during btrfs_read_qgroup_config and meant to be used later by the qgroup accounting code. However, it is always freed before btrfs_read_qgroup_config returns, becuase the commit mentioned above adds a check for (ret), where a check for (ret < 0) would have been the right choice. This commit fixes the check.
