That is not a bug - please look at Jens replies in this thread some week ago. In short, queue_depth=1 means 1 tags in total and reserved_tags=1 results in zero normal tags. You need to request the depth=2 and reserved_tags=1. But yes, this is a separate topic and I am looking forward to hear from Jens wrt flushes. -- Regards, Alexander Gordeev agord...@redhat.com -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
