    perf bpf: Show more BPF program info in print_bpf_prog_info() · f8dfeae0
    Song Liu authored
    This patch enables showing bpf program name, address, and size in the
    header.
    
    Before the patch:
    
      perf report --header-only
      ...
      # bpf_prog_info of id 9
      # bpf_prog_info of id 10
      # bpf_prog_info of id 13
    
    After the patch:
    
      # bpf_prog_info 9: bpf_prog_7be49e3934a125ba addr 0xffffffffa0024947 size 229
      # bpf_prog_info 10: bpf_prog_2a142ef67aaad174 addr 0xffffffffa007c94d size 229
      # bpf_prog_info 13: bpf_prog_47368425825d7384_task__task_newt addr 0xffffffffa0251137 size 369
    
    Committer notes:
    
    Fix the fallback definition when HAVE_LIBBPF_SUPPORT is not defined,
    i.e. add the missing 'static inline' and add the __maybe_unused to the
    args. Also add stdio.h since we now use FILE * in bpf-event.h.
