implementing UFS storage will not use LED 2.

The generic disk activity trigger is usually registered. I guess this is because UFS lives in SCSI and SCSI does not call ledtrig_disk_activity() when stuff happens on a SCSI device.

ATA and IDE does... I think it's just a matter of patching something inside drivers/scsi/* and it should work fine with UFS too. It should have been done ages ago, just noone did it.

I would do it if I had a SCSI or UFS system running but I don't.
