    It seems IRQF_SHARED | IRQF_DISABLED has already been discussed several
    times on LKML:


    Especially this message


    makes me think that Linus will reject my proposed patch for the lockup
    problem as it implements choice (c) on his list.

    Alan: should I try to implement his choice (f) insteadn, i.e. drop
    IRQF_DISABLED from USB HCD interrupts and disable interrupts in
    usb_hcd_irq() instead?
