SELinux: hold tasklist_lock and siglock while waking wait_chldexit SELinux has long been calling wake_up_interruptible() on current->parent->signal->wait_chldexit without holding any locks. It appears that this operation should hold the tasklist_lock to dereference current->parent and we should hold the siglock when waking up the signal->wait_chldexit.
