mm/damon: add trace event for auto-tuned monitoring intervals
Patch series "mm/damon: add trace events for auto-tuned monitoring
intervals and DAMOS quota".
The aim-oriented auto-tuning features for monitoring intervals and DAMOS
quota are important and recommended. Add tracepoints for observabilities
of those tuned values and the tuning itself.
This patch (of 2):
Aim-oriented monitoring intervals auto-tuning is an important and
recommended feature for DAMON users. Add a trace event for the
observability of the tuned intervals and tuning itself.
