Subject: [PATCH v2 01/17] btrfs-progs: lowmem check: release path in repair_extent_data_item()
Date: Wed, 20 Dec 2017 12:57:15 +0800	[thread overview]
Message-ID: <20171220045731.19343-2-suy.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <20171220045731.19343-1-suy.fnst@cn.fujitsu.com>

In repair_extent_data_item(), path is not be released if some
errors occurs which causes extent buffer leak.

So release path in end of the function.
