Wang Nan a5b8bd47dc bpf tools: Collect eBPF programs from their own sections ... This patch collects all programs in an object file into an array of 'struct bpf_program' for further processing. That structure is for representing each eBPF program. 'bpf_prog' should be a better name, but it has been used by linux/filter.h. Although it is a kernel space name, I still prefer to call it 'bpf_program' to prevent possible confusion. bpf_object__add_program() creates a new 'struct bpf_program' object. It first init a variable in stack using bpf_program__init(), then if success, enlarges obj->programs array and copy the new object in.
