This patches set improves bpf_perf (perf-stat --bpf-counter) by 1) exposing key definitions to a libperf header; 2) adding compatibility check for perf_attr_map; 3) introducing config stat.bpf-counter-events.
Changes v1 => v2: 1. Separte 2/3 from 1/3. (Jiri) 2. Rename bperf.h to bpf_perf.h. (Jiri) 3. Other small fixes/optimizations.
