OK. I'll add document like below.
What: /sys/class/leds/<led>/interval
Date: Aug 2019
KernelVersion: 5.4
Contact: linux-leds@vger.kernel.org
Description:
Specifies the duration of the LED blink in milliseconds.
Defaults to 50 ms.
What: /sys/class/leds/<led>/read
Date: Aug 2019
KernelVersion: 5.4
Contact: linux-leds@vger.kernel.org
Description:
Signal data read on the block device.
If set to 0, the LED will not blink on data read.
If set to 1 (default), the LED will blink for the milliseconds
specified in interval to signal data read.
What: /sys/class/leds/<led>/write
Date: Aug 2019
KernelVersion: 5.4
Contact: linux-leds@vger.kernel.org
Description:
Signal data written on the block device.
If set to 0, the LED will not blink on data written.
If set to 1 (default), the LED will blink for the milliseconds
specified in interval to signal data written.
What: /sys/class/leds/<led>/discard
Date: Aug 2019
KernelVersion: 5.4
Contact: linux-leds@vger.kernel.org
Description:
Signal data discarded on the block device.
If set to 0, the LED will not blink on data discarded.
If set to 1 (default), the LED will blink for the milliseconds
specified in interval to signal data discarded.
