    So I don't think your patch is quite right.

    If you want to clear the IRQF_ONESHOT for MSI irq's (and other ones
    where the interrupt controller is fundamentally ONESHOT), I think you
    should do it a few lines higher up - *before* you check the "does the
    IRQF_ONESHOT mask match other shared interrupts"?

    Now, irq sharing presumably doesn't happen with MSI, but there's
    nothing fundamentally wrong with message-based irq schemes that have
    shared interrupt handlers.

    I think. Hmm?
