Subject: [PATCH linux-next] cgroup: use strscpy() is more robust and safer
Date: Wed, 21 Sep 2022 09:35:17 +0000 [thread overview]
Message-ID: <20220921093517.230745-1-ye.xingchen@zte.com.cn> (raw)
From: ye xingchen <ye.xingchen@zte.com.cn>
The implementation of strscpy() is more robust and safer.
That's now the recommended way to copy NUL terminated strings.
