commit a2ab909933f8c8623282979dfa64f3e358bdb9fc
Author: Andi Kleen <ak@gargoyle.(none)>

    Make scheduler sysfs attributes sysdev class devices
    
    They are really class devices, but were incorrectly declared. This leads
    to crashes with the recent changes that makes non normal sysdevs
    use a different prototype.
