Subject: [PATCH 1/9] Docs/admin-guide/mm/damon/usage: use sysfs interface for tracepoints example

DAMON tracepoints example on the DAMON usage document is using DAMON

sysfs interface.

 While the monitoring is turned on, you could record the tracepoint events and
 show results using tracepoint supporting tools like ``perf``.  For example::
 
-    # echo on > monitor_on
+    # echo on > kdamonds/0/state
     # perf record -e damon:damon_aggregated &
     # sleep 5
     # kill 9 $(pidof perf)
