- * Get bpf_prog_info in continuous memory
- *
- * struct bpf_prog_info has multiple arrays. The user has option to choose
- * arrays to fetch from kernel. The following APIs provide an uniform way to
- * fetch these data. All arrays in bpf_prog_info are stored in a single
- * continuous memory region. This makes it easy to store the info in a
- * file.
- *
- * Before writing bpf_prog_info_linear to files, it is necessary to
- * translate pointers in bpf_prog_info to offsets. Helper functions
- * bpf_program__bpil_addr_to_offs() and bpf_program__bpil_offs_to_addr()
- * are introduced to switch between pointers and offsets.
- *
- * Examples:
- *   # To fetch map_ids and prog_tags:
- *   __u64 arrays = (1UL << BPF_PROG_INFO_MAP_IDS) |
- *           (1UL << BPF_PROG_INFO_PROG_TAGS);
- *   struct bpf_prog_info_linear *info_linear =
- *           bpf_program__get_prog_info_linear(fd, arrays);
- *
- *   # To save data in file
- *   bpf_program__bpil_addr_to_offs(info_linear);
- *   write(f, info_linear, sizeof(*info_linear) + info_linear->data_len);
- *
- *   # To read data from file
- *   read(f, info_linear, <proper_size>);
- *   bpf_program__bpil_offs_to_addr(info_linear);
