[PATCH 0/8] Docs: damon: fix grammar and typos

[Aveline Noir]

I was reading the DAMON docs and kept running into small grammar
mistakes and typos, so here is a series that tries to clean them up.
There is one patch per document, and nothing beyond grammar was
changed :)

Some fixes pushed lines over 80 columns, so those paragraphs are
rewrapped.  Patch 4 picks up what I think was left in lru_sort.rst
after Manuel's recent fix.

Based on damon/next at 9d301805e3f6.

Thanks,
Aveline Noir

[PATCH 1/8] Docs/admin-guide/mm/damon/start: fix grammar

[Aveline Noir]

Fix a few grammar slips in the getting-started guide, like "make DAMON
monitors" and a region "that has not accessed".

"The line of the commands" used to be "The first two lines".  With only
one masim line left, I make it "The first line".

My intention was saying DAMO is commanding DAMON to monitor the process.  So I
find Aveline's version is slightly better.

Looks good.  Unless Aveline objects or do this by themselves with revisioning,
I will add this change when I apply this patch to damon/next.

Agreed. Both "start" and "make" depend on "asks DAMO to", so I'd keep
"make" here.

"converts it" refers to the access events, so I think it should be
"them".  Rewrap the paragraph while at it.

[PATCH 3/8] Docs/admin-guide/mm/damon/usage: fix grammar

Fix a handful of grammar mistakes in the usage doc, mostly
subject-verb agreement and a missing or extra "be".  Also turn "Below
commands applies" into "The commands below apply", which I think reads
better.  Rewrap where the lines got too long.

[PATCH 4/8] Docs/admin-guide/mm/damon/lru_sort: fix remaining grammar

[Aveline Noir]

Manuel's recent grammar fix for this file, now in damon/next, covered a
good part of it.  This should take care of the few mistakes that are
left, like "should automatically activated" and "Make DAMON_LRU_SORT
reads".  Rewrap where the lines got too long.

Agreed. The plural "descriptions" reads better here.

I think "has been exceeded" fits here, since the subject is the
singular "time quota limit". The same applies to cold regions.

[PATCH 5/8] Docs/mm/damon/design: fix grammar and typos

[Aveline Noir]

The design doc has quite a few relative clauses that seem to have lost
their verb, like "pages that assumed to have" or "filters that handled
by the core layer".  Fix those, along with some agreement issues and a
couple of typos: "Parreto", and "Use space", which I think should be
"User space".  Rewrap where the lines got too long.

[PATCH 8/8] Docs/mm/damon/monitoring_intervals_tuning_example: fix grammar and typos

[Aveline Noir]

Fix a few typos, including "Moniting" in the title, and some grammar in
the interval tuning example.

"starts looking degrading" should be "start looking degraded for", as I
think the sentence means the cold region detection starts to look worse.
Rewrap where the lines got too long.
