Laurence,

I ended up going a slightly different route. Instead of adding your
clarifying paragraph, I fixed the places where the module parameter was
incorrectly written (i.e. missing the scsi_mod. prefix).

+Additional notes on passing parameters on the command line:
+
+It's not intuitively obvious how to pass certain parameters on the boot line.
+For parameters such as scsi_dev_flags, you need to pass these to the scsi_mod as 
+the following example for the scsi_dev_flags.

+On kernel line add scsi_mod.dev_flags=LIO-ORG:thin2:0x8000000
