Docs/admin-guide/mm/damon/usage: describe the rules of sysfs region directories

Browse source 
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.

@ -235,6 +235,9 @@ In each region directory, you will find two files (``start`` and ``end``). You
can set and get the start and end addresses of the initial monitoring target
region by writing to and reading from the files, respectively.
Each region should not overlap with others. ``end`` of directory ``N`` should
be equal or smaller than ``start`` of directory ``N+1``.
