...t: scsi: sg: fix v3 compat read/write interface" 2. Four patches for missing block compat_ioctl handlers, to be backported into stable kernels. Separate patches because they are needed in different stable versions. 3. Actually moving handlers out of block/compat_ioctl.c and block/scsi_ioctl.c into drivers, mixed in with cleanup patches 4. Document how to do this right. I keep getting asked about this, and it helps to point to some documentation file. The series is avaialable for testing at [1].

Each driver calling scsi_ioctl() gets an equivalent compat_ioctl() handler that implements the same commands by calling scsi_compat_ioctl(). The scsi_cmd_ioctl() and scsi_cmd_blk_ioctl() functions are compatible at this point, so any driver that calls those can do so for both native and compat mode, with the argument passed thr...

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
