From 87775312a86bcf213e3b21f6f7c79e2e00d96f7b Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Thu, 2 Jul 2015 16:30:24 +0200 Subject: [PATCH] net-ipv6: Delete an unnecessary check before the function call "free_percpu" 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. Signed-off-by: Markus Elfring Signed-off-by: David S.
