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

The following patches were made over Linus's tree and fix an issue where windows guests will send iovecs with offset/lengths that result in IOs that are not aligned to 512. The LIO layer will then send them to Linux's FS/block layer but it requires 512 byte alignment, so depending on the FS/block driver being used we will get IO errors or hung IO. The following patches have vhost-scsi

OK, this is (ab)uses some of Paolo's patches. The first 7 are candidates for this merge window (maybe), the rest I'm not so sure about. Thanks, Rusty.
