Sure they do. Everything that calls ll_rw_block() or submit_bh() will go through generic_make_request. Neil, you're probably thinking about __make_request(), which only triggers for "normal" devices. The fact that the buffer doesn't go through generic_make_request() implies that it is some buffer that is completely internal to the raid5 processing. I don't see anything like that, though. Jasper, sorry about even asking this, but where did you add the check for b_end_io? Maybe you put it in __make_request() by mistake?
