Subject: Docs/ABI/damon: document update_tuned_intervals state command
Date: Tue, 14 Jul 2026 07:01:15 -0700

The 'update_tuned_intervals' command of the 'state' file, added in commit
1077605396b4 ("mm/damon/sysfs: implement a command to update auto-tuned
monitoring intervals"), is described in usage.rst but missing from the
canonical ABI document.  Add it.
