Time for me to learn Coccinelle:
http://coccinelle.lip6.fr
and download and install it. (An ed script could probably do a lot of it, but
it's past time to get Coccinelle into my toolkit.)

We don't guarantee API compatibility between major or dot releases, only
between dot-dot releases.

{add,get}_persistent_proto_data()
{add,get}_per_layer_packet_info()
or something such as that. The scope isn't relevant, the *purpose of the data*
is relevant, and dictates the scope to use.
(It also removes the possibility to get the scope wrong, using a scope not
supported by the routines.)
