This series fixes typos and fills in missing entries in the DAMON sysfs ABI document (Documentation/ABI/testing/sysfs-kernel-mm-damon). Patch 1 fixes a path typo, "intrvals_goal" -> "intervals_goal", in four What: entries; the documented path points to a non-existent directory, so it is Cc'ed to stable. Patch 2 fixes two further typos ("WDate:", "manimum"). Patches 3 and 4 add ABI entries that exist in the kernel and are already described in usage.rst but are missing from the canonical ABI document: the 'update_tuned_intervals' state command (patch 3) and the 'tried_regions//probes/

/hits' file (patch 4). This patch (of 4): The ABI document spells the DAMON sysfs directory as "intrvals_goal" (missing 'e') in four What: entries, but the kernel creates it as "intervals_goal" (mm/damon/sysfs.c). Following the documented path therefore yields a non-existent directory.
