Subject: [PATCH 10/22] mm/damon/lru_sort: use monitoring attributes parameters generaotr macro
Date: Tue, 13 Sep 2022 17:44:37 +0000	[thread overview]
Message-ID: <20220913174449.50645-11-sj@kernel.org> (raw)
In-Reply-To: <20220913174449.50645-1-sj@kernel.org>

This commit makes DAMON_LRU_SORT to generate the module parameters for
DAMON monitoring attributes using the generator macro to simplify the
code and reduce duplicates.
