    you are getting them because interrupts get disabled somewhere in the
    path. Do your changes perhaps introduce a local_irq_save() or
    local_irq_disable()?

    (in PREEMPT_REALTIME spin_lock_irq*() does not disable interrupts for
    mutex-based spinlocks, so the only way to get irqs disabled is
    explicitly.)
