From d0057ca4c1fe73c05a9e077cc7691217370b3283 Mon Sep 17 00:00:00 2001 From: David Rientjes Date: Tue, 8 Apr 2014 16:04:13 -0700 Subject: [PATCH] arch/x86/mm/kmemcheck/kmemcheck.c: use kstrtoint() instead of sscanf() Kmemcheck should use the preferred interface for parsing command line arguments, kstrto*(), rather than sscanf() itself. Use it appropriately.
