I assume he means put sg under sd, that can't be done as sg is at the same
level as sd, and can even show up if sd is not loaded (and shows up for
all scsi devices, not just block ones ...).
If all your scsi devices are block devices, you likely can run without
loading sg, and just send SG_IO ioctl's to the block device.
sg does show up under the sys device tree, as the "generic" link:
[elm3b79 0:0:0:0]$ ls -l /sys/devices/pci0000:00/0000:00:0a.0/host0/target0:0:0/0:0:0:0/generic
lrwxrwxrwx 1 root root 0 May 31 17:54 /sys/devices/pci0000:00/0000:00:0a.0/host0/target0:0:0/0:0:0:0/generic -> ../../../../../../class/scsi_generic/sg0
