Should > this not go into include/linux/perf_event.h ? Not that I care much, but this one has perf_event_attach_bpf_prog() and perf_event_detach_bpf_prog(), so it felt appropriate to put it here. perf_event.h only seems to have perf_event_bpf_event() for BPF-related stuff (which seems to be just notification events, not really BPF functionality per se). But let me know if you prefer to add these new ones to perf_event.h.
