    SubjectRe: [RFC PATCH] cfq-iosced: Implement IOPS mode and group_idle tunable V3
    To me this sounds like slice_idle=0 is the right default then, as it
    gives useful behaviour for all systems linux runs on. Setups with
    more than a few spindles are for sure more common than setups making
    use of cgroups. Especially given that cgroups are more of a high end
    feature you'd rarely use on a single SATA spindle anyway. So setting
    a paramter to make this useful sounds like the much better option.

    Especially given that the block cgroup code doesn't work particularly
    well in presence of barriers, which are on for any kind of real life
    production setup anyway.
