Is anyone working on SCSI passthrough using the ''SCSI Generic'' support under Linux, eg /dev/sgX? This is how VMWare allows a VM to use SCSI devices.

Hi all, this series builds on my previous changes in Jens' for-4.11/rq-refactor branch that split out the BLOCK_PC fields from struct request into a new struct scsi_request, and makes support for struct scsi_request and the SCSI passthrough ioctls optional. It is now only enabled by drivers that need it. In addition I've made SCSI passthrough support in the virtio_blk driver an optional
