Subject: [PATCH] UBIFS: add missing znode freeing in tcn_insert()
Date: Fri, 7 Mar 2014 16:11:27 -0800	[thread overview]
Message-ID: <1394237487-2728-1-git-send-email-f.fainelli@gmail.com> (raw)

In case the zi allocation fails in the do_split label, we will fail
freeing zn that we allocated before, add a missing kfree.
