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.

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.
