BPF_PROG_LOAD #

Processed by bpf_prog_load, which:

1. Checks the permission, the flags, license compatibility;
2. Initializes a struct bpf_prog;
3. Runs the verifier with bpf_check;
4. Tries to JIT the program with bpf_prog_select_runtime;
5. Allocates an ID to the program, and maybe calls bpf_prog_kallsyms_add (no idea what it does).
