Subject: [PATCH 06/10] block: convert kyber latency show to sysfs_emit()
Date: Wed, 1 Apr 2026 15:07:12 +0800 [thread overview]
Message-ID: <20260401070716.991-7-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 the KYBER_LAT_SHOW_STORE
macro for the kyber I/O scheduler latency target show functions.
