Subject: signals: do_signal_stop: kill the SIGNAL_UNKILLABLE check
From: Oleg Nesterov <oleg@xxxxxxxxxx>
fae5fa44f1fd079ffbed8e0add929dd7bbd1347f changed do_signal_stop() to check
SIGNAL_UNKILLABLE, this wasn't needed. If signal_group_exit() == F, the
signal sent to SIGNAL_UNKILLABLE task must be already filtered out by the
caller, get_signal_to_deliver(). And if signal_group_exit() == T we are
not going to stop.
