Please descide on a naming scheme for the frontend modules.  You have
tcm_loop for thise one, and just iscsi for the iscsi frontend.

Ok, curently everything that appears under drivers/target/ beside
iscsi_target_mod.ko is using a matching drivers/target/$FABRIC_MOD/ and
$FABRIC_MOD.ko naming scheme.

I would prefer to keep iscsi_target_mod.ko for the software iSCSI case
in order to prevent chaos with existing userspace tools and prevent
breakage with existing other iSCSI target modules (IET is using
iscsi_trgt.ko IIRC).

How about dropping the 'tcm_' prefix from the drivers/target/tcm_subdir/
to follow how the fabric module actually appears once loaded under
/sys/kernel/config/target/$FABRIC/..?  We will need to keep the common
'tcm_' prefix for the actual target fabric modules (or choose a
different one) to handle those that interface with existing SCSI LLD
code.

Dropping the tcm sounds fine to me.

This makes it a bit easier to grok as a reference for newcomers by
having seperate sections for configfs control plane, struct
target_core_fabric_ops API callers, and Linux/SCSI LLD specific glue.

I don't think it's a very good reference, though.  E.g. currently the
fabric ops methods are implemented in tcm_loop_fabric.c, and all need
non-static scope because they are assigned in tcm_loop_configfs.c, which
creates a lot of global scope and pointless prototypes.  Either one
could clean all that up or just merge the files into one which would
be a lot easier.  Especiall as the way the target_fabric_configfs structure
and the fabric ops are structured will get a big overhaul from me soon.

Ok, fair enough..  I will go ahead and look at getting this cleaned up.

In the mean time, James please go ahead and apply patches #1 -> #20 from
this target core series to scsi-misc as I have no futher changes to
report at this time.  I will send out an updated PATCH 21/21 addressing
Christoph's comments for merging tcm_loop.ko shortly, and another RFC-v3
series addressing his comments for the initial iscsi_target_mod merge in
the next 24 hours.
