Subject: [PATCH 3/5] btrfs-progs: missing tree-freeing statements added
Date: Thu, 5 Sep 2013 10:38:56 +0800	[thread overview]
Message-ID: <1378348738-14451-4-git-send-email-guihc.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <1378348738-14451-1-git-send-email-guihc.fnst@cn.fujitsu.com>

The seen cache_tree in run_next_block freed.
Originally, this "missing" causes memory leaks, reported by valgrind.
