Actually, instread of a private member I'd simply pass struct stm_data
pointer to the callback (like we do with other callbacks) and the
private data would be in the structure that embeds this struct stm_data,
so that you can get to it using container_of():
struct my_stm {
struct stm_data data;
void *my_stuff;
...
};
...
long my_ioctl(struct stm_data *data, unsigned int cmd, unsigned long
arg)
{
struct my_stm *mine = container_of(data, struct my_stm, data);
...
Would this work for you? I'm otherwise ready to send the second version
of my patchset.
