There are devices (like the KD20) which got 2 LEDs for each S-ATA port:
a red one to indicate a faulty disk and a blue to indicate link-up and
port activity.

Will, I wrote this patch a long while ago (and use it on oxnas)

https://git.lede-project.org/?p=source.git;a=blob;f=target/linux/generic/patches-4.9/834-ledtrig-libata.patch

Maybe this LED trigger could take a parameter from userspace to
indicate the mount-status as well (unless there is a way to get
use-count from inside the libata subsystem?)

Anyway, I tried submitting this upstream and it was deleted from their
patchwork within a day with no reason given what-so-ever, I guess
because they believe that the generic 'disk' led-trigger is good
enough...
