[stgt] stgt target kernel component

[charles zhuang]

Hi,
I have a question regarding stgt target kernel components.
I think for iscsi tcp and iscsi iser, everything is in user space, so I only need tgtd daemon with tgtadm to configure it. Is my understanding correct?
If so, what modification that stgt project has done to linux kernel side and when do we need the kernel components? My guess is that the kernel components are only needed in srp, which we need scsi_tgt.ko (tgt core) and scsi_transport_srp.ko. Is it correct?
Thanks for any tips. 
I am looking for a solution that I can move the iscsi state machine back to kernel, so really appreciate if there's some more elaboration on how scsi_tgt.ko core interact with the kernel.

 Thanks,
charles
