		<description><![CDATA[Dear Linux Hackers, Have we not finished changing the &#8216;best&#8217; way to have persistent naming and security attributes for disk devices? Seriously, just when we thought it was great to put the &#8220;uid&#8221;, &#8220;gid&#8221; and &#8220;mode&#8221; specifications for disk devices into /etc/multipath.conf, then it gets once again deprecated in favour of udev.

One of the things that I have struggled to get data for in my storage research is the latency of the interface between server and storage device. It&#8217;s easy to get numbers for the actual storage device, but the latency numbers [...]]]></description>
