Re: [PATCH v4 2/2] selftests: Add test for overriding global data value before load

This adds a test to exercise the new bpf_map__set_initial_value() function.
The test simply overrides the global data section with all zeroes, and
checks that the new value makes it into the kernel map on load.

I guess given you don't attach or run any BPF program, it's fine to
reuse test_global_data.o for this.
