   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.

Ingo/Linus?
