How do you avoid it for the async case? We can only call ki_complete once all bios have finished, which means we need a tracking structure for it. For the synchronous case we could in theory wait for the previous bio before sending the next, but there are plenty of RAID arrays that would prefer > 1MB I/O. And we can pretty much reuse the async case for this anyway. -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
