This patch adds funnel_queue, a mostly lock-free multi-producer,
single-consumer queue. It also adds the request queue used by the dm-vdo
deduplication index, and the work_queue used by the dm-vdo data store. Both
of these are built on top of funnel queue and are intended to support the
dispatching of many short-running tasks. The work_queue also supports
priorities. Finally, this patch adds vdo_completion, the structure which is
enqueued on work_queues.
