similar to: [PATCH] virtio-blk: remove VIRTIO_BLK_F_SCSI support

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

Without this fix attempts to do scsi passthrough on virtio_blk will crash the system on virtually mapped stacks, which is something happening during boot with many distros.

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. Paolo Bonzini (3): scatterlist: introduce sg_unmark_end virtio-blk: reorganize virtblk_add_req virtio-blk: use virtqueue_add_sgs on req path Rusty Russell (13): virtio_ring: virtqueue_add_sgs, to add multiple sgs. virtio-blk:

Add virtqueue_add_sgs which is more general than virtqueue_add_buf, which makes virtio-scsi and virtio-blk nicer, then add virtqueue_add_inbuf and virtqueue_add_outbuf which handle the more general case, and finally delete virtqueue_add_buf(). I'm hoping this will be the final post of the whole series, and it can move from my pending-rebases tree into virtio-next. Thanks! Rusty. Paolo

Most device drivers do not need to perform any postprocessing on the scatterlists they receive from higher-level drivers (e.g. the block or SCSI layer), because they translate the request metadata directly from the various C structs into the data that is required by the device. virtio devices however do this translation in two steps: a device-specific step in the device driver, and generic
