'Modules' section
'Programmable Modules' section provides high level descriptions of the
DAMON API-based kernel modules layer. But 'Modules' section, which is at
the end of the document, provides every detail about the layer including
that of 'Programmable Modules' section.
Since the brief summary of the layers at the beginning of the document has
a link to the 'Modules' section, browsing to the section is not that
difficult. Remove 'Programmable Modules' section in favor of 'Modules'
section and reducing duplicates.

'Operations Set Layer' section
'Configurable Operations Set' section is for providing a description of
the pluggability of the operations set layer. Just after that,
'Operations Set Layer' section, which is dedicated for the entire things
of the layer, follows. The layout is odd, and some descriptions are
duplicated. Move 'Configurable Operations Set' section into 'Operations
Set Layer' and re-write some of the detailed descriptions.

DAMON design document briefly explains the overall layers architecture
first, and then provides detailed explanations of each layer with
dedicated sections. Letting readers go directly to the detailed sections
for specific layers could help easy browsing of the not-very-short
document. Add links from the overall summary to the sections of details.

Patch series "Docs/damon: minor fixups and improvements".
Fixup typos, clarify regions merging operation design with recent change,
add access pattern snapshot example use case, and improve readability of
the design document and subsystem documents index by
reorganizing/wordsmithing and adding links to other sections and/or
documents for easy browsing.
This patch (of 9):
Fix two typos. The first one is just a simple typo: s/accurach/accuracy/
The second one is made by the author being out of their mind. 'Region
Based Sampling' section of the doc is mistakenly calling the access
frequency counter of region as 'nr_regions'. Fix it with the correct
name, 'nr_accesses'.

DAMON bi-weekly community meetup series has continued since 2022-08-15 for
community members who prefer synchronous chat over asynchronous mails.
Recently I got some feedbacks about the series from a few people. They
told me the series is helpful for understanding of the project and
particiapting to the development, but it could be further better in terms
of the visibility. Based on that, I started sending meeting reminder for
every occurrence. For people who don't subscribe the mailing list,
however, adding an announcement on the official document could be helpful.
Document the series on DAMON maintainer's profile for the purpose.

Patch series "Docs/mm/damon/maintaier-profile: document a mailing tool and
community meetup series", v2.
There is a mailing tool that developed and maintained by DAMON
maintainer aiming to support DAMON community. Also there are DAMON
community meetup series. Both are known to have rooms of improvements
in terms of their visibility. Document those on the maintainer's
profile document.
This patch (of 2):
Since DAMON was merged into mainline, I periodically received some
questions around DAMON's mailing lists based workflow. The workflow is
not different from the normal ones that well documented, but it is also
true that it is not always easy and familiar for everyone.
I personally overcame it by developing and using a simple tool, named
HacKerMaiL (hkml)[1]. Based on my experience, I believe it is matured
enough to be used for simple workflows like that of DAMON. Actually some
DAMON contributors and Linux kernel developers other than myself told me
they are using the tool.
As DAMON maintainer, I also believe helping new DAMON community members
onboarding to the worklow is one of the most important parts of my
responsibilities. For the reason, the tool is announced[2] to support
DAMON community. To further increasing the visibility of the fact,
document the tool and the support plan on DAMON maintainer's profile.

The document mentions any patches for review should based on mm-unstable
instead of damon/next. It should be the recommended process, but
sometimes patches based on damon/next could be posted for some reasons.
Actually, the DAMON-based tiered memory management patchset[1] was written
on top of 'young page' DAMOS filter patchset, which was in damon/next tree
as of the writing.
Allow such case and just ask such things to be clearly specified.

MADV_PAGEOUT
The doc needs a fix. As only in the case of virtual address, we are
calling madvise() with MADV_PAGEOUT. But in the case of physical address,
we are calling reclaim_pages() directly. MADV_PAGEOUT on virtual address
is much more aggresive to reclaim memory compared to reclaim_pages() on
paddr region. This patch removes the details so that the description can
apply to both cases. And we don't need to couple with the implementation
details.

and focus on only the usage. Move the list to design document and update
