Subject: [RFC PATCH 3/3] Docs/admin-guide/mm/damon/usage: update for tried regions update time interval
Date: Tue, 10 Oct 2023 01:26:00 +0000	[thread overview]
Message-ID: <20231010012600.83140-4-sj@kernel.org> (raw)
In-Reply-To: <20231010012600.83140-1-sj@kernel.org>

The documentation says DAMOS tried regions update feature of DAMON sysfs
interface is doing the update for one aggregation interval after the
request is made.  Since the introduction of the per-scheme apply
interval, that behavior makes no much sense.  Hence the implementation
has changed to update the regions for each scheme for only its apply
interval.  Further update the document to reflect the real behavior.
