Kumar Kartikeya Dwivedi 9805af8d8a bpf: Document UAPI details for special BPF types ... The kernel recognizes some special BPF types in map values or local kptrs. Document that only bpf_spin_lock and bpf_timer will preserve backwards compatibility, and kptr will preserve backwards compatibility for the operations on the pointer, not the types supported for such kptrs. For local kptrs, document that there are no stability guarantees at all. Finally, document that 'bpf_' namespace is reserved for adding future special fields, hence BPF programs must not declare types with such names in their programs and still expect backwards compatibility.
