Oleg Nesterov 3581832971 vm_is_stack: use for_each_thread() rather then buggy while_each_thread() ... commit 4449a51a7c281602d3a385044ab928322a122a02 upstream. Aleksei hit the soft lockup during reading /proc/PID/smaps. David investigated the problem and suggested the right fix. while_each_thread() is racy and should die, this patch updates vm_is_stack().
