Subject: Docs/admin-guide/mm/damon/usage: describe the rules of sysfs region directories
Date: Mon, 24 Oct 2022 17:46:18 +0000
Patch series "Docs/admin-buide/mm/damon/usage: minor fixes".
DAMON usage document contains an unclear description and a wrong usage
example. This patchset fixes the two minor problems.
This patch (of 2):
Target region directories of DAMON sysfs interface should contain no
overlap and sorted by the address, but not clearly documented. Actually,
a user had an issue[1] due to the poor documentation. Add clear
description of it on the usage document.
