From 08a9b9857fc2d77600f09f3d342f6c64d25083b2 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 11 May 2015 11:41:17 -0300 Subject: [PATCH] perf kmem: Fix compiler warning about may be accessing uninitialized variable The last argument to strtok_r doesn't need to be initialized, its just a placeholder to make this routine reentrant, but gcc doesn't know about that and complains, breaking the build, fix it by setting it to NULL.
