    I skipped the last version of this because KOSAKI Motohiro
    <kosaki.motohiro@jp.fujitsu.com> said "Please attach blktrace analysis ;)".

    I'm not sure why he asked for that, but he's a smart chap and
    presumably had his reasons.

    If you think that such an analysis is unneeded, or isn't worth the time
    to generate then please tell us that. But please don't just ignore the
    request!

    Thanks.
