Konrad Rzeszutek Wilk 97961ef46b xen/blkback: Move the plugging/unplugging to a higher level. ... We used to the plug/unplug on the submit_bio. But that means if within a stream of WRITE, WRITE, WRITE,...,WRITE we have one READ, it could stall the pipeline (as the 'submio_bio' could trigger the unplug_fnc to be called and stall/sync when doing the READ). Instead we want to move the unplugging when the whole (or as a much as possible) ring buffer has been processed. This also eliminates us doing plug/unplug for each request.
