    cputime: Use accessors to read task cputime stats · 6fac4829
    Frederic Weisbecker authored
    This is in preparation for the full dynticks feature. While
    remotely reading the cputime of a task running in a full
    dynticks CPU, we'll need to do some extra-computation. This
    way we can account the time it spent tickless in userspace
    since its last cputime snapshot.
