Re: remove connections notification by conntrack?

Hi - i'm rather new to this list and trying to learn as much as I can about 
this API. I see that for this particular function, there are no API docs. You 
make reference to "unofficial API docs" on a website, but shouldn't there be 
actual proper doc comments before the function? i.e.

/** @param  this - a reference to a notifier block, which will be used for ???
     @param events - a bitmask - please see ifnetlink.h for the possible 
values
     @param ptr - a pointer to a struct ip_conntrack for the purposes of ???
     @return it seems to return NOTIFY_DONE under every possible exec path.

static int ctnetlink_conntrack_event(struct notifier_block *this,
                                     unsigned long events, void *ptr)
