Message-ID: <5479E693.3010200@users.sourceforge.net> Date: Sat, 29 Nov 2014 16:30:27 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: netdev@...r.kernel.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH 1/1] net-ipvlan: Deletion of an unnecessary check before the function call "free_percpu" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Sat, 29 Nov 2014 16:23:20 +0100 The free_percpu() 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.
