Subject: [PATCH 04/22] mm/damon/core: factor out 'damos_quota' private fileds initialization
Date: Tue, 13 Sep 2022 17:44:31 +0000 [thread overview]
Message-ID: <20220913174449.50645-5-sj@kernel.org> (raw)
In-Reply-To: <20220913174449.50645-1-sj@kernel.org>
The 'struct damos' creation function, 'damon_new_scheme()', does
initialization of private fileds of 'struct damos_quota' in it. As its
verbose and makes the function unnecessarily long, this commit factors
it out to separate function.
