  "message": "Block driver using virtio.\n\nThe block driver uses scatter-gather lists with sg[0] being the\nrequest information (struct virtio_blk_outhdr) with the type, sector\nand inbuf id.  The next N sg entries are the bio itself, then the last\nsg is the status byte.  Whether the N entries are in or out depends on\nwhether it\u0027s a read or a write.\n\nWe accept the normal (SCSI) ioctls: they get handed through to the other\nside which can then handle it or reply that it\u0027s unsupported.  It\u0027s\nnot clear that this actually works in general, since I don\u0027t know\nif blk_pc_request() requests have an accurate rq_data_dir().\n\nAlthough we try to reply -ENOTTY on unsupported commands, ioctl(fd,\nCDROMEJECT) returns success to userspace.  This needs a separate\npatch.\n\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n",
