Subject: [PATCH 14/17] btrfs-progs: fix mem leak in resolve_root
Date: Mon, 25 Feb 2013 16:54:47 -0600	[thread overview]
Message-ID: <1361832890-40921-15-git-send-email-sandeen@redhat.com> (raw)
In-Reply-To: <1361832890-40921-1-git-send-email-sandeen@redhat.com>

If we exit with error we must free the allocated memory
to avoid a leak.
