    The use of the 'ignore_nice' sysfs file is confusing to anyone using. This
    patch makes it so when you now set it to the default value of 1, process nice
    time is also ignored in the cpu 'busyness' calculation. We also rename
    'ignore_nice' to 'ignore_nice_task' so that userland tools notice the inverse
    behaviour sooner.

    Prior to this patch to set it to '1' to make process nice time count...even
    confused me :)

    WARNING: this obvious breaks any userland tools that expect things to be the
    other way round; hence why, as suggested, the rename of the 'ignore_nice'
    file to 'ignore_nice_tasks'
