Subject: [PATCH] ext4: remove unnecessary gotos in ext4_xattr_set_entry
Date:   Fri, 31 May 2019 15:10:16 +0300
Message-Id: <20190531121016.11727-1-ptikhomirov@virtuozzo.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In the "out" label we only iput old/new_ea_inode-s, in all these places
these variables are always NULL so there is no point in goto to "out".
