The include files that come from open-iscsi that are in the kernel do
not have the iBFT data structures in them - therefore no duplication.
I think that consolidating is not necessary. Adding in the iSCSI IBFT
structs (and the module's internal structs) are not essential for
the iSCSI module. From this module standpoint, it is not using
anything from the iSCSI kernel module and its friends so why should it
important a module from there?
Lastly it would also mean the setup_[32|64].c file would have
to include a header file from the iSCSI (linux/scsi/iscsi_proto.h) for the
'find_ibft' prototype. That seems excessive for one function prototype.

It definitly does. The next version of this patch is named 'ibft_eth_end_marker'.

Added in the 'ibft_tgt_end_marker' as well.

No. They do have different names. But I re-did this function a bit
to prepare it for the new function 'kobject_init_and_add' and
to handle error unrolling much better (and free at the right moment the
ibft_kobj structure).

Yikes! Thanks for spotting that.
New version (v0.4.2) coming out shortly.
