I find a couple of LED triggers that I can't find their function of.

They are rfkill0 rfkill-none and rfkill-any.

Who can explain their subtle differences? Please do.

Documentation is of course failing, but as I understood it:

rfkill0             Flash on wifi activity
rfkill1             Flash on bluetooth activity
rfkill-any          Flash on any activity (wifi or bluetooth)
rfkill-none         Never understood that one
