Subject: [PATCH] fs: nfs: sysfs: use sysfs_emit() to instead of scnprintf()
Date: Mon, 5 Dec 2022 17:19:16 +0800 (CST)	[thread overview]
Message-ID: <202212051719169589575@zte.com.cn> (raw)

From: ye xingchen <ye.xingchen@zte.com.cn>

Follow the advice of the Documentation/filesystems/sysfs.rst and show()
should only use sysfs_emit() or sysfs_emit_at() when formatting the
value to be returned to user space.
