[Qemu-devel] [PATCH 0/2] Introduce a new vhost-user-blk device and sample application |

Since vhost-user-scsi device has been part of Qemu, many users are still
using old virtio_blk device in Guest OS, compared with vhost-user-scsi,
vhost-user-blk can get better performance, because eliminate one SCSI_MOD
kernel module. This patch provides another option for uses to implement
their own I/O stacks.
Due to virtio_blk protocol limitation, Qemu virtio_blk frontend device can't
get Capacity/block size parameters through protocol, users must pass them
when started Qemu. Of course, we can extend exist vhost user messages to add
2 more messages(get_block_config/set_block_config) for vhost-user-blk device.
But for this patch, we choose append parameters to Qemu vhost-user-blk as the
solution.
