What DAMON aims to do is not only access monitoring but efficient and
effective access-aware system operations. And DAMon-based Operation
Schemes (DAMOS) is the important feature of DAMON for the goal. Make
the intro of DAMON documentation to emphasize the goal and mention
DAMOS.

+For easier development of such systems, DAMON provides a feature called DAMOS
+(DAMon-based Operation Schemes) in addition to the monitoring. Using the
+feature, DAMON users in both kernel and user spaces can do access-aware system
+operations with no code but simple configurations.
