Slightly off topic and while I don't forget about it.. Please find
attached a copy of the patch posted around [1] to be able to define
injection points with input arguments, so as it is possible to execute
callbacks with values coming from the code path where the point is
attached.
For example, a backend could use this kind of macro to have a callback
attached to this point use some runtime value:
INJECTION_POINT_1ARG("InjectionPointBoo", &some_value);
