    sched/cputime: Convert task/group cputime to nsecs · 5613fda9
    Frederic Weisbecker authored
    Now that most cputime readers use the transition API which return the
    task cputime in old style cputime_t, we can safely store the cputime in
    nsecs. This will eventually make cputime statistics less opaque and more
    granular. Back and forth convertions between cputime_t and nsecs in order
    to deal with cputime_t random granularity won't be needed anymore.
