+quota_mem_pressure_us
+---------------------
+
+Desired level of memory pressure-stall time in microseconds.
+
+While keeping the caps that set by other quotas, DAMON_RECLAIM automatically
+increases and decreases the effective level of the quota aiming this level of
+memory pressure is incurred. System-wide ``some`` memory PSI in microseconds
+per quota reset interval (``quota_reset_interval_ms``) is collected and
+compared to this value to see if the aim is satisfied. Value zero means

+quota_autotune_feedback
+-----------------------
+
+User-specifiable feedback for auto-tuning of the effective quota.
+
+While keeping the caps that set by other quotas, DAMON_RECLAIM automatically
+increases and decreases the effective level of the quota aiming receiving this
+feedback of value ``10,000`` from the user. DAMON_RECLAIM assumes the feedback
+value and the quota are positively proportional. Value zero means disabling
