(and this causes a missed softirq.) an irq that could mark the softirq active under entry.S will also run do_softirq itself before iret to entry.S. If the softirq remains active after an irq it it because it was marked active again under do_softirq and ksoftirq is the way to go for fixing that case I think. Andrea
