Subject: [PATCH bpf-next 0/2] bpftool improvements for xlated dump

This work adds correlation of maps and calls into the bpftool
xlated dump in order to help debugging and introspection of
loaded BPF progs. First patch makes kallsyms work on subprogs
with bpf calls, and second implements the actual correlation.
Details and example output can be found in the 2nd patch.

Thanks a lot!

Daniel Borkmann (2):
  bpf: fix kallsyms handling for subprogs
  bpf: allow for correlation of maps and helpers in dump
