I can't load the SCSI driver as a module, because drivers/scsi/scsi.h
references 'req_finished_io' and this function is not exported by
driver/block/ll_rw_blk.c where it is defined.
Known problem. You can add an EXPORT_SYMBOL(req_finished_io) to the end of this
rebuild from make dep and it will fix the problem.
