But that check was only for discard (and discard-like) bios which had the maic single page that sometimes was unused attached. For "normal" bios the for_each_segment loop iterates over bi_vcnt, so it will be ignored anyway. That being said both I and the lists got CCed halfway through the thread and I haven't seen the original report, so I'm not really sure what's going on here anyway. -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
