Hm, to check what? Not sure I can parse this sentence at a glance.

So you changed 'tools perf' to 'perf tools', but you should probably find a better name for 'tools lib bpf' as well, say:
bpf tools: Define basic interface
?

'ELF' is not a noun really. From ELF binaries? From ELF sections?

so 'of' bpf_program, but 'for' struct bpf_object?
