Description
-----------
DAMON provides damon_aggregated tracepoint to let users record full monitoring
results. Sometimes, users need to record monitoring results of specific
pattern. DAMOS tried regions directory of DAMON sysfs interface allows it, but
the interface is mainly designed for snapshots and therefore would be
inefficient for such recording. Implement yet another tracepoint for efficient
support of the usecase.
