The style is copied from lib traceevent. I'll change it as your suggestion.

Thanks a lot. I changed titles again:

  tools lib traceevent: Install libtraceevent.a into libdir
  tools: Change FEATURE_TESTS and FEATURE_DISPLAY to weak binding
  tools: Add __aligned_u64 to types.h
  bpf tools: Introduce 'bpf' library to tools
  bpf tools: Allow caller to set printing function
  bpf tools: Define basic interface
  bpf tools: Open eBPF object file and do basic validation
  bpf tools: Check endianess and set swap flag according to EHDR
  bpf tools: Iterate over ELF sections to collect information
  bpf tools: Collect version and license from ELF sections
  bpf tools: Collect map definitions from 'maps' section
  bpf tools: Collect config string from 'config' section
  bpf tools: Collect symbol table from SHT_SYMTAB section
  bpf tools: Collect eBPF programs from their own sections
  bpf tools: Collect relocation sections from SHT_REL sections
  bpf tools: Record map accessing instructions for each program
  bpf tools: Clear libelf and ELF parsing resrouce to finish opening
  bpf tools: Add bpf.c/h for common bpf operations
  bpf tools: Create eBPF maps defined in an object file
  bpf tools: Relocate eBPF programs
  bpf tools: Introduce bpf_load_program() to bpf.c
  bpf tools: Load eBPF programs in object files into kernel
  bpf tools: Introduce accessors for struct bpf_program
  bpf tools: Introduce accessors for struct bpf_object
  perf tools: Add new 'perf bpf' command
  perf tools: Make perf depend on libbpf
  perf bpf: Add 'perf bpf record' subcommand
  perf bpf: Add bpf-loader and open ELF object files
  perf bpf: Collect all eBPF programs
  perf bpf: Parse probe points of eBPF programs during preparation
  perf bpf: Probe at kprobe points
  perf bpf: Load all eBPF object into kernel
  perf tools: Add a bpf_wrapper global flag
  perf tools: Add bpf_fd field to evsel and introduce new event syntax
  perf bpf: Generate event argv for other commands
  perf bpf: Pass generated arguments to cmd_record()

Do you have further suggestion?

Thank you.
