Subject: [RFC bpf-next 0/2] bpf: add a kallsyms BPF iterator

a kallsyms BPF iterator would be useful as it would allow more flexible
iteractions with kernel symbols than are currently supported; it could
for example create more efficient map representations for lookup,
speed up symbol resolution etc.

The idea was initially discussed here [1].
