Users who manually check the files under the DAMON debugfs directory could notice the deprecation owing to the 'DEPRECATED' DAMON debugfs file, but there could be users who doesn't manually check the files. Make the deprecation cannot be ignored in the case by renaming 'monitor_on' file, which is essential for real use of DAMON on runtime, to 'monitor_on_DEPRECATED'. Still users who control DAMON via only user-space tool could ignore the deprecation, but that's what the tool developers should take care of. DAMON user-space tool, damo, has also made a change[1] for the purpose.
