Subject: [PATCH 1/1] fs-namei: Deletion of an unnecessary check before the function call "iput"
Date: Sat, 29 Nov 2014 17:03:54 +0100 [thread overview]
Message-ID: <5479EE6A.8080904@users.sourceforge.net> (raw)
In-Reply-To: <5317A59D.4@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 29 Nov 2014 17:00:21 +0100
The iput() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
