Subject: [PATCH 0/3] leds: trigger: Add led trigger for bpf
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.
