DAMON is not only for monitoring of access patterns, but also for access-aware system operations. For the system operations, DAMON provides a feature called DAMOS (Data Access Monitoring-based Operation Schemes). There is no sample API usage of DAMOS, though. Copy the working set size estimation sample modules with changed names of the module and symbols, to use it as a skeleton for a sample module showing the DAMOS API usage. The following commit will make it proactively reclaim cold memory of the given process, using DAMOS.

This builds DAMON sample module for working set size estimation.

The module receives a pid, monitor access to the virtual address

space of the process, estimate working set size of the process, and

repeatedly prints the size on the kernel log.
