[PATCH 4/5] NVMe: add blk polling support

2015-11-06 Thread Jens Axboe
Add nvme_poll(), which will check a specific completion queue for command completions. Wire that up to the new block layer poll mechanism. Later on we'll setup specific sq/cq pairs that don't have interrups enabled, so we can do more efficient polling. As of this patch, an IRQ will still trigger
