[Duplicate Text] in mm/damon/ and Doc/admin-guide/mm/damon/

[Manuel Ebner]

Hi SJ,

there is a lot of duplicated text in these directories. Diff doesn't show
any because in mm/damon/ the text is a multi-line comment.

~40 Lines in lru_sort.c and lru_sort.rst,
~50 Lines in reclaim.c and reclaim.rst and
a few Lines in stat.c and stat.rst.

I think it's important to decide on how to handle the duplication before
patching.

Delete one set, keep (and fix) both or add a reference in one place to
the other? Could sphinx do the duplication?

Thanks
 Manuel
