2026-01-07rtla/timerlat: Add example for BPF action programTomas Glozar
Add an example BPF action program that prints the measured latency to the tracefs buffer via bpf_printk(). A new Makefile target, "examples", is added to build the example. In addition, "sample/" subfolder is renamed to "example". If BPF skeleton support is unavailable or disabled, a warning will be displayed when building the BPF action program example.
