True. Doubling the amount of triggers is probably not a good idea.

I agree. Especially since Jacek pointed out that some triggers do that
already.

I think all kinds of activity indicators (disk-activity, mmc, usb, ide,
nand, cpu, network, etc.) make sense. Guess I'll add a flags field to
the led_trigger struct and have an invertible flag that specifies
whether a trigger should be invertible or not.


Thanks again,
