2a91cb2d2b Docs/translations/*/admin-guide/mm/damon/usage: remove DAMON debugfs interface documentation 
Patch series "mm/damon: remove DAMON debugfs interface".

DAMON debugfs interface was the only user interface of DAMON at the
beginning[1].  However, it turned out the interface would be not good
enough for long-term flexibility and stability.

In Feb 2022[2], we therefore introduced DAMON sysfs interface as an
alternative user interface that aims long-term flexibility and stability. 
With its introduction, DAMON debugfs interface has announced to be
deprecated in near future.

In Feb 2023[3], we announced the official deprecation of DAMON debugfs
interface.  In Jan 2024[4], we further made the deprecation difficult to
be ignored.

In Oct 2024[5], we posted an RFC version of this patch series as the last
notice.

And as of this writing, no problem or concerns about the removal plan have
reported.  Apparently users are already moved to the alternative, or made
good plans for the change.

Remove the DAMON debugfs interface code from the tree.  Given the past
timeline and the absence of reported problems or concerns, it is safe
enough to be done.

This patch (of 8):

It's time to remove DAMON debugfs interface, which has deprecated long
before in February 2023.  Read the cover letter of this patch sereis for
more details.

Remove DAMON debugfs interface usage documentation and references to it
from translations, to avoid confusing users with documents for already
removed things.

00cba6b60f docs/admin-guide/mm: remove useless markup 
It is enough to use a file name to cross-reference another rst document.

Jon says:
  The right things will happen in the HTML output, readers of the
  plain-text will know immediately where to go, and we don't have to add
  the label clutter.

Drop reference markup and unnecessary labels and use plain file names.

Pull MM updates from Andrew Morton:
 "Most of the MM queue. A few things are still pending.

  Liam's maple tree rework didn't make it. This has resulted in a few
  other minor patch series being held over for next time.

  Multi-gen LRU still isn't merged as we were waiting for mapletree to
  stabilize. The current plan is to merge MGLRU into -mm soon and to
  later reintroduce mapletree, with a view to hopefully getting both
  into 6.1-rc1.

  Summary:

   - The usual batches of cleanups from Baoquan He, Muchun Song, Miaohe
     Lin, Yang Shi, Anshuman Khandual and Mike Rapoport

   - Some kmemleak fixes from Patrick Wang and Waiman Long

   - DAMON updates from SeongJae Park

   - memcg debug/visibility work from Roman Gushchin

   - vmalloc speedup from Uladzislau Rezki

   - more folio conversion work from Matthew Wilcox

   - enhancements for coherent device memory mapping from Alex Sierra

   - addition of shared pages tracking and CoW support for fsdax, from
     Shiyang Ruan

   - hugetlb optimizations from Mike Kravetz

   - Mel Gorman has contributed some pagealloc changes to improve
     latency and realtime behaviour.

   - mprotect soft-dirty checking has been improved by Peter Xu

   - Many other singleton patches all over the place"
