[RFC PATCH 1/5] block: Introduce q->abort_queue_fn()
When user hot-unplug a disk which is busy serving I/O, __blk_run_queue
might be unable to drain all the requests. As a result, the
blk_drain_queue() would loop forever and blk_cleanup_queue would not
return. So hot-unplug will fail.
This patch adds a callback in blk_drain_queue() for low lever driver to
abort requests.
Currently, this is useful for virtio-blk to do cleanup in hot-unplug.
