|
In class_handle_hash() if a cookie of zero is really so dangerous then perhaps it shouldn't be used. h->h_cookie = handle_base;
if (unlikely(handle_base == 0)) {
/*
* Cookie of zero is "dangerous", because in many places it's
* assumed that 0 means "unassigned" handle, not bound to any
* object.
*/
CWARN("The universe has been exhausted: cookie wrap-around.\n");
handle_base += HANDLE_INCR;
}
