[PATCH bpf-next v2 08/20] bpf: implement common macros/helpers for target iterators

Macro DEFINE_BPF_ITER_FUNC is implemented so target can define an init function to capture the BTF type which represents the target. The bpf_iter_meta is a structure holding meta data, common to all targets in the bpf program. Additional marker functions are called before/after bpf_seq_read() sho
