KOSAKI Motohiro fa18f7bde3 posix-cpu-timers: don't account cpu timer after stopped thread runtime accounting ... When tsk->signal->cputimer->running is 1, signal->cputimer (i.e. per process timer account) and tsk->sum_sched_runtime (i.e. per thread timer account) increase at the same pace because update_curr() increases both accounting. However, there is one exception. When thread exiting, __exit_signal() turns over task's sum_shced_runtime to sig->sum_sched_runtime, but it doesn't stop signal->cputimer accounting. This inconsistency makes POSIX timer wake up too early. This patch fixes it.
