Ingo, In reading your -U3 patch the test below (#156) wasn't clear to me. It would seem in the case of softirq_preemption, __do_softirq() should be called to kick ksoftirqd, otherwise ___do_softirq() would be called to exec softirqs in the immediate context.
kernel/softirq.c:
153 asmlinkage void _do_softirq(void) 154 { 155 local_irq_disable(); 156 if (!softirq_preemption) 157 __do_softirq(); 158 else 159 ___do_softirq(); 160 local_irq_enable(); 161 }
