From 442cc432e68b24dc6bd70b1ee1f5d477ee1aa385 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 12 Dec 2014 16:57:18 -0800 Subject: [PATCH] mm/zswap: delete unnecessary check before calling free_percpu() free_percpu() 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.
