Looking at the scsi_transport_*.c files... Are these part of the lower layer
or the midlayer? I _think_ these exist primarily to expose information about
the lower layers through sysfs, but I'm very fuzzy on this...
Should they be documented as part of the lower layer or the midlayer or are
they their own area...?

They're part of the mid layer (the lower layer is simply all the
drivers).

They should be documented on their own. They're basically service
libraries and sysfs export helpers for drivers.

^^^^^^^
(Rob, in case it's not already clear from context, James is referring
with "drivers" only to low-level drivers here, not to the high-level
drivers sd, sg, sr, st, osst, ch.)
