Subject: [PATCH -next 3/3] ocfs2: Replaced simple_strtoull() with kstrtoull()
Date: Wed, 26 May 2021 09:20:20 +0000 [thread overview]
Message-ID: <20210526092020.554341-3-chenhuang5@huawei.com> (raw)
In-Reply-To: <20210526092020.554341-1-chenhuang5@huawei.com>
The simple_strtoull() function is deprecated in some situation since
it does not check for the range overflow, use kstrtoull() instead.
