  "message": "dataplane: replace internal thread with IOThread\n\nToday virtio-blk dataplane uses a 1:1 device-per-thread model.  Now that\nIOThreads have been introduced we can generalize this to N:M devices per\nthreads.\n\nThis patch drops thread code from dataplane in favor of running inside\nan IOThread AioContext.\n\nAs a bonus we solve the case where a guest keeps submitting I/O requests\nwhile dataplane is trying to stop.  Previously the dataplane thread\nwould continue to process requests until the request gave it a break.\nNow we can shut down in bounded time thanks to\naio_context_acquire/release.\n\nSigned-off-by: Stefan Hajnoczi \u003cstefanha@redhat.com\u003e\n",
