Subject: [PATCH 07/10] block: convert bfq_var_show() to sysfs_emit()
Date: Wed, 1 Apr 2026 15:07:13 +0800 [thread overview]
Message-ID: <20260401070716.991-8-liu.yun@linux.dev> (raw)
In-Reply-To: <20260401070716.991-1-liu.yun@linux.dev>
From: Jackie Liu <liuyun01@kylinos.cn>
Use sysfs_emit() instead of sprintf() in bfq_var_show(), which is
the common helper used by all BFQ sysfs show functions.
