3 nit picks:

Other "fields" are separated by two spaces between each other:

  4: kprobe  name func_begin  tag 57cd311f2e27366b license GPL compatible

Could you also update the example outputs in the man page:

tools/bpf/bpftool/Documentation/bpftool-prog.rst

Sorry about the bike shedding but I would also vote for:

"[not] GPL compatible"

rather than

"license GPL [NON] compatible"

for brevity..
