I have a rough sketch of a patch to do that, and I was going to send it out today, but the test machine caught on fire while I was hammering it with the fsync tests one last time and ... yeah. I'm fairly sure the patch didn't cause the fire, but I'll check anyway after I finish cleaning up. "[PATCH] ext4: Don't set my machine ablaze with barrier requests" :P (The patch did seem to cut barrier requests counts by about 20% though the impact on performance was pretty small.) --D -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
