    Subject2.6.32 / RH 6.1 scheduler bloated
    Date
    A simple ftrace wakeup test shows 10us latency during the idle-to-run
    transition:

    # tracer: wakeup
    #
    # wakeup latency trace v1.1.5 on 2.6.32-131.0.15.el6.x86_64

    <idle>-0 6d.h.. 0us : 0:120:R + [006] 30: 0:R
    watchdog/6
    <idle>-0 6d.h.. 1us+: wake_up_process <-watchdog_timer_fn
    <idle>-0 6d.... 10us : thread_return <-cpu_idle
    <idle>-0 6d.... 10us : 0:120:R ==> [006] 30: 0:R
    watchdog/6


    I've cheched several processes, they all show the same approx delay.
    Red Hat 6.1 is compiled with ftrace enabled by default, anybody can
    run this test:

    # mount -t debugfs nodev /sys/kernel/debug
    # cd /sys/kernel/debug/tracing
    # echo wakeup > current_tracer
    # echo myprocpid > set_ftrace_pid
    # echo 1 > tracing_enabled
    ...
    # cat trace

    dmesg output
