Ah, good. Can't understand why I didn't think about this before!
But, perhaps, it is better to add the new helper, __send_signal()
or whatever which has the new "from_ancestor_ns" argument. Then,
static int send_signal(...)
{
bool from_ancestor_ns = 0;
#ifdef CONFIG_PID_NS
if (!is_si_special(info) && SI_FROMUSER(info)) {
from_ancestor_ns = !task_pid_nr_ns(current, task_active_pid_ns(t));
}
#endif
return __send_signal(..., from_ancestor_ns);
}
but this is cosmetic issue.
Oleg.
