Subject: [PATCH v2 bpf-next 0/4] bpf: per program stats

Introduce per program stats to monitor the usage BPF

v1->v2:
- fixed u64 stats on 32-bit archs. Thanks Eric
- use more verbose run_time_ns in json output as suggested by Andrii
- refactored prog_alloc and clarified behavior of stats in subprogs

Alexei Starovoitov (4):
  bpf: enable program stats
  bpf: expose program stats via bpf_prog_info
  tools/bpf: sync bpf.h into tools
  tools/bpftool: recognize bpf_prog_info runtime and runcnt
