From b69deb2b7e13f04da5c0684c7ce19e788736ab0d Mon Sep 17 00:00:00 2001 From: Zhang Zhen Date: Wed, 6 Aug 2014 16:06:06 -0700 Subject: [PATCH] mm/mem-hotplug: replace simple_strtoull() with kstrtoull() Use the newer and more pleasant kstrtoull() to replace simple_strtoull(), because simple_strtoull() is marked for obsoletion.
