+====================
+BPF LED Trigger
+====================
+
+This LED trigger is useful for triggering LEDs from the BPF subsystem. This
+trigger is designed to be used in combination with a BPF program that interacts
+with the trigger via a kfunc. The exported kfuncs will have BTF names that
+start with "bpf_ledtrig_".
+
+The trigger can be activated from user space on led class devices as shown
+below::
+
+ echo bpf > trigger
