WebBPF_MAP_TYPE_PROG_ARRAY (since Linux 4.2) A program array map is a special kind of array map whose map values contain only file descriptors referring to other eBPF programs. Thus, both the key_size and value_size must be exactly four bytes. This map is used in conjunction with the bpf_tail_call () helper.

The name BTF was used initially to describe data types. The BTF was later extended to include function info for defined subroutines, and line info for source/line information.
