Due to the lack of an entry for the Japanese translation of
documentation, Kosuke Fujimoto needed to ask the status of
its maintenance [1].

Add an entry for DOCUMENTATION/JAPANESE as a sub-subsystem
under the DOCUMENTATION subsystem to make it easier for
another prospective contributor to know there is someone
who takes care of Japanese translation.

As a first step, install myself as a designated reviewer.
Hopefully, other interested members get accustomed to the
kernel-dev workflow and would get ready to be
(co-)maintainers/reviewers shortly.

The unit mentioned in the documentation of scheduler statistics is
outdated which may mislead the readers.

The unit of statistics that is reported by /proc/schedstat is modified
to nanosecond, and the unit of statistics that is reported by
/proc/PID/schedstat is provided as well to make the context consistent.

The rq_cpu_time and the rq_sched_info.run_delay of a run queue, and the
sched_info.run_delay of a task are all updated based on the clock of the
run queue, while the se.sum_exec_runtime of a task is updated based on
the clock_task of the run queue of the task. Both the clock and
clock_task are relied on the return value of the function sched_clock()
which is in the unit of nanosecond.
