Further more, holding a lock_irq doesn't mean bottom halves are disabled
too, it just means interrupts are disabled and no *new* softirq can be
queued. Consider the following situation:
I think local_bh_enable() should check irqs_disabled() and honour that.
What you are showing here, that BH's can run via local_bh_enable()
even when IRQs are disabled, is a BUG().
IRQ disabling is meant to be stronger than softint disabling.
