Subject: [PATCH] staging: lustre: Fix an error handling path in 'client_common_fill_super()'
Date:   Sat, 12 May 2018 08:33:05 +0200
Message-Id: <20180512063305.7339-1-christophe.jaillet@wanadoo.fr>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

According to error handling path before and after this one, we should go
to 'out_md_fid' here, instead of 'out_md', if 'obd_connect()' fails.

The last goto 'out_lock_cn_cb' looks spurious but is correct.
In case of error, 'd_make_root()' performs a 'iput()', so skipping it in
the error handling path lokks fine to me.
