Juergen Gross 95af4cb3d0 xen/events: increment refcnt only if event channel is refcounted ... [ Upstream commit d277f9d828 ] In bind_evtchn_to_irq_chip() don't increment the refcnt of the event channel blindly. In case the event channel is NOT refcounted, issue a warning instead. Add an additional safety net by doing the refcnt increment only if the caller has specified IRQF_SHARED in the irqflags parameter.
