[Xen-devel] [PATCH] xen/events/fifo: Add missing hotplug notifier transition

2016-03-11 Thread Anna-Maria Gleixner
The evtchn_fifo_cpu_notification() hotplug callback lacks handling of the CPU_UP_CANCELED case. That means, if CPU_UP_PREPARE fails, the handle of the fifo events is not dropped. Add handling for CPU_UP_CANCELED transition to drop the fifo events handle. Cc: Konrad Rzeszutek Wilk Cc: Boris Ostro
