> However I have seen buggy code where spin_lock_irq() was issued with > interrupts disabled. [...] Some time ago I sent a patch to lkml that tests for this [1]. And guess what - it happens all over the place [2]. Also, the scheduler often gets called with interrupts disabled (schedule() does spin_lock_irq), but the cases I checked all turned out to be OK [3]. Perhaps it is more problematic now? Ciao, Duncan.
