Subject: Disabling an interrupt in interrupt context

I have a need to disable an LSI interrupt from within the context of the handler for that interrupt.  It appears that disable_irq_nosync() will do the trick.  Besides dropping interrupts, which I don't care about because the device is in an error state, what are the potential side effects of doing this?  As far as I can tell, this will not prevent the current in-flight handlers for that interrupt from finishing.

Thanks,
Mike Mason
