Docs/admin-guide/mm/damon/usage: use sysfs interface for tracepoints example
Patch series "mm/damon: make DAMON debugfs interface deprecation
unignorable".
DAMON debugfs interface is deprecated in February 2023, by commit
5445fcbc4cda ("Docs/admin-guide/mm/damon/usage: add DAMON debugfs
interface deprecation notice"). Make the fact unable to be easily ignored
by removing an example usage from the document (patch 1), renaming the
config (patch 2), adding a deprecation notice file to the debugfs
directory (patches 3-5), and renaming the debugfs file that essnetial to
be used for real use of DAMON (patches 6-9).
This patch (of 9):
DAMON tracepoints example on the DAMON usage document is using DAMON
debugfs interface, which is deprecated. Use its alternative, DAMON sysfs
interface.
