...internal to the driver. It cannot just use the one that was prepared by the upper SCSI layers. This series adds a different set of APIs for adding a buffer to a virtqueue. The new API lets you pass the buffers piecewise, wrapping multiple calls to virtqueue_add_sg between virtqueue_start_buf and virtqueue_end_buf. Letting drivers call virtqueue_add_sg multiple times if they already have a scatterlist provided by someone else simplifies the code and, for virtio-scsi, it saves the copying and the related locking. One major difference between virtqueue_add_buf and virtqueue_add_sg is that the latter uses sca...

Hi all, this series adds multiqueue support to the virtio-scsi driver, based on Jason Wang's work on virtio-net. It uses a simple queue steering algorithm that expects one queue per CPU. LUNs in the same target always use the same queue (so that commands are not reordered); queue switching occurs when the request being queued is the only one for the target. Also based on Jason's
