Chen Liang a6afe518a8 sched/fair: fix bug: remove printk while schedule is in progress ... It will cause deadlock and while(1) if call printk while schedule is in progress. The block state like as below: cpu0(hold the console sem): printk->console_unlock->up_sem->spin_lock(&sem->lock)->wake_up_process(cpu1) ->try_to_wake_up(cpu1)->while(p->on_cpu). cpu1(request console sem): console_lock->down_sem->schedule->idle_banlance->update_cpu_capacity-> printk->console_trylock->spin_lock(&sem->lock). p->on_cpu will be 1 forever, because the task is still running on cpu1, so cpu0 is blocked in while(p->on_cpu), but cpu1 could not get spin_lock(&sem->lock), it is blocked too, it means the task will running on cpu1 forever.
