OK, well at first glance, the locking around device_blocked and
host_blocked looks pointless.  What are the failure traces you're using
to decide they need spinlock protection?

The blk_plug_queue change looks reasonable ... however, blk_plug_queue
itself looks like it might not entirely need the queue lock ... I need
to investigate more closely.
