Yeah, we thought about that.

It's still not clear that tgt iSCSI target driver (*1) is accepted to
mainline. We can use lots of parts of open-iscsi code for it, however,
you can say that iSCSI target software can be implemented in user

Mike said that returning from vacation, he clean up and submit the
iSCSI target driver to scsi-ml for discussion.

If we fail to put it into mainline, I'll implement iscsi target
software in user space, which uses tgt user-space code (SCSI
processing, management, etc). So, is it possible that we integrate
iSER into user-space iSCSI target software?

*1) the iSCSI (tcp) target driver for tgt (which partially works)
