# ls /sys/module/sg/parameters/
allow_dio  def_reserved_size  scatter_elem_sz

# ls /proc/scsi/sg/
allow_dio  debug  def_reserved_size  device_hdr  devices  device_strs
red_debug  version

So that doesn't work, what are in 'parameters' are passed in at
module/driver initialization. Back to my original question: Could the
contents of /proc/scsi/sg/* be placed in /sys/class/scsi_generic/* ?
