Subject: [RFC PATCH 4/9] mm/damon/core: use damos_quota_is_set() in damos_adjust_quota()
Date: Sat, 12 Sep 2026 13:08:05 -0700 [thread overview]
Message-ID: <20260912200814.145612-5-sj@kernel.org> (raw)
In-Reply-To: <20260912200814.145612-1-sj@kernel.org>
damos_adjust_quota() is manually checking if the user set the DAMOS
quota. There is a dedicated helper, damos_quota_is_set(), for the
purpose. Use the helper.
