Subject: [PATCH] mm/mem-hotplug: replace simple_strtoul() with kstrtoul()
Date: Thu, 19 Jun 2014 15:50:03 +0800 [thread overview]
Message-ID: <53A2962B.9070904@huawei.com> (raw)
In-Reply-To: <1403151749-14013-1-git-send-email-zhenzhang.zhang@huawei.com>
use the newer and more pleasant kstrtoul() to replace simple_strtoul(),
because simple_strtoul() is marked for obsoletion.
