Original BPF token patch set ([0]) added delegate_xxx mount options which supported only special "any" value and hexadecimal bitmask. This patch set attempts to make specifying and inspecting these mount options more human-friendly by supporting string constants matching corresponding bpf_cmd, bpf_map_type, bpf_prog_type, and bpf_attach_type enumerators. This is an RFC patch set and I've only converted bpf_cmd enum to be generated through reusable mapper macro. If the consensus is that this approach is the way to go, adding similar support for three remaining enums is just a matter of mundane mechanical conversion in UAPI header. Kernel-side logic for all delegate_xxx mount options is completely generic already as implemented in patch #1.
