Subject: [PATCH 08/12] Btrfs: Fix memory leak on finding existing super
Date: Thu, 27 Jan 2011 16:44:54 +0800 [thread overview]
Message-ID: <4D413086.10109@cn.fujitsu.com> (raw)
In-Reply-To: <4D412FE6.7050101@cn.fujitsu.com>
From: Ian Kent <raven@themaw.net>
We missed a memory deallocation in commit 450ba0ea.
If an existing super block is found at mount and there is no
error condition then the pre-allocated tree_root and fs_info
are no not used and are not freeded.
