This patch set adds a new led trigger that uses the bpf subsystem for triggering leds. It is designed to be used in conjunction with a bpf program(s) that can modify led state through the use of bpf kfuncs. This is useful for providing a physical indication that a some event has occurred. In the context of bpf this could range from handling a packet to hitting a tracepoint.
