[PATCH v2 4/4] virtio-blk: remove batch notification BH

2023-08-17 Thread Stefan Hajnoczi
There is a batching mechanism for virtio-blk Used Buffer Notifications that is no longer needed because the previous commit added batching to virtio_notify_irqfd(). Note that this mechanism was rarely used in practice because it is only enabled when EVENT_IDX is not negotiated by the driver.
