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 compile time feature, as it's not actually needed for most
common setups.
