For multi-touch devices the frontend needs to initialize the correct
number of slots for touch tracking. Hardware drivers do this by
calling input_mt_init_slots() on initialization. For virtio_input
the function must be called when the backend sends ABS_MT_SLOT.

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 mod
