I have structures defined as such in the code base but this is a problem for 
the work I want to do. 

struct save_ops {
    void (*start_copy)(void *data, const char *filename);
    void *(*copy_finished)(const char *filename);
    void (*check_copied)(void *data);
};

The aim of my patch is to define the following functions from the above struct

 
void hvm_start_copy(void *data, const char *filename);
void *hvm_copy_finished(const char *filename);
void hvm_check_copied(void *data);

void pv_start_copy(void *data, const char *filename);
void *pv_copy_finished(const char *filename);
void pv_check_copied(void *data);

The python m_rule I have permits me to match the list of function pointers
and the python script permits me to rename the pointers to the function names
as I have them here. Having at least the pv functions will be good for me. 

The issue now is to be able to write these to the resulting patch.
