It might be possible to replace proto_peekremote / add NEW_PROTO_TREE_API define before config.h include.

Still if we're no longer forced to have header_field_info in register routine, I was thinking we could put hfi just before use.
You can check sample in packet-netlink-sock_diag.c, which I base on packet-mpeg-descriptor.c

Also Peter suggested some modification to create HFI_REG_VAR macro[1].


btw. recently I have been doing some research if it's possible to do this kind of optimization using clang/ gcc plugins.
Right now I have no code.
