    SubjectDynamically determine if kernel includes CFS Scheduler
    I've received an internal request for a means to determine at run-time 
    if the CFS scheduler is included in the running kernel. Looking through
    the git commit log and the /proc/sys/kernel filesystem, I think I see
    two approaches:

    1) stat("/proc/sys/kernel/sched_compat_yield")
    This confirms 2.6.23-rc7 kernel or later which definitely has the CFS
    scheduler and this functionality is of interest anyway.
    2) Test if the kernel version is >= 2.6.22 which is where I believe CFS

    Any guesses as to how robust/future-proof approach #1 would be?
