Subject: [PATCH v2 4/8] Docs/admin-guide/mm/damon/lru_sort: fix remaining grammar
Date: Mon, 2 Nov 2026 16:59:34 -0800 [thread overview]
Message-ID: <20261103005940.91432-5-sj@kernel.org> (raw)
In-Reply-To: <20261103005940.91432-1-sj@kernel.org>
From: Aveline Noir <jm5905938@gmail.com>
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.
