Subject: [PATCH v3 0/2] bpftool: improve error handing for missing .BTF section

Display error message for missing ".BTF" section and clean up empty
vmlinux.h file.

v3:
 - fix typo and make error message consistent. (Andrii Nakryiko)
 - split out perf change.
v2:
 - remove vmlinux specific error info.
 - use builtin target .DELETE_ON_ERROR: to delete empty vmlinux.h


Changbin Du (2):
  libbpf: show error info about missing ".BTF" section
  bpf: makefiles: do not generate empty vmlinux.h
