Auto-tune monitoring intervals
------------------------------
If this parameter is set as ``Y``, DAMON_LRU_SORT automatically tunes DAMON's
sampling and aggregation intervals. The auto-tuning aims to capture meaningful
amount of access events in each DAMON-snapshot, while keeping the sampling
interval 5 milliseconds in minimum, and 10 seconds in maximum. Setting this as
``N`` disables the auto-tuning.
Disabled by default.
