Alan, the usage of cancel_delayed_work() in drivers/ata/libata-core.c looks
suspicious to me, both ->hotplug_task and ->port_task can re-arm themselves,
so cancel_delayed_work + flush_workqueue (or cancel_work_sync) is not enough.
Could you confirm/nack my understanding?
For all rearming workqueues, one must use cancel-rearming-blahblah.
