If that state was EXIT_DEAD (or another cpu\ndoes sys_wait4) interrupted task has -\u003esignal \u003d\u003d NULL.\n\nAt this moment exiting task has no pending cpu timers, they were cleaned\nup in __exit_signal()-\u003eposix_cpu_timers_exit{,_group}(), so we can just\nreturn from irq.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
