Yes, REPORT LUNS is quite essential. It's not exactly in the same category as reporting device form factor and rotational speed. If REPORT LUNS is wrong, we're in really deep trouble. If device form factr is wrong ... umm ... nothing much happens. If rotational speed is wrong, we might have a suboptimal IO pattern. It's also fixable by udev. The current check for is_ssd (that doesn't check the version) was put in for 2.6.27. It doesn't appear to have caused any trouble. -- Matthew Wilcox Intel Open Source Technology Centre "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
