Subject: [PATCH linux-next] scsi: smartpqi: use strscpy() to instead of strncpy()
Date: Mon, 26 Dec 2022 19:01:55 +0800 (CST) [thread overview]
Message-ID: <202212261901554408949@zte.com.cn> (raw)
From: Xu Panda <xu.panda@zte.com.cn>
The implementation of strscpy() is more robust and safer.
That's now the recommended way to copy NUL-terminated strings.
