Subject: [Ocfs2-devel] [PATCH -next 1/3] powerpc/rtas: Replaced simple_strtoull() with kstrtoull()
Date: Wed, 26 May 2021 09:20:18 +0000	[thread overview]
Message-ID: <20210526092020.554341-1-chenhuang5@huawei.com> (raw)

The simple_strtoull() function is deprecated in some situation, since
it does not check for the range overflow, use kstrtoull() instead.
