Apparently, not close enough. Nothing in the commit message mentioned
returning instructions. I skimmed the patch and filled in that GET_INFO
was returning just the meta-data.

If we don't agree on the problem, we won't be able to agree on the
solution.
I want the ability to retrieve the BPF instructions pushed to the

This patch series:
1) Introduce ID for both bpf_prog and bpf_map.
2) Add bpf commands to iterate the prog IDs and map
IDs of the system.
3) Add bpf commands to get a prog/map fd from an ID
4) Add bpf command to get prog/map info from a fd.
The prog/map info is a jump start in this patchset
