Subject: [RFC PATCH 5/9] mm/damon/sysfs: use damon_call() for commit_schemes_quota_goals
Date: Fri, 13 Dec 2024 13:53:02 -0800	[thread overview]
Message-ID: <20241213215306.54778-6-sj@kernel.org> (raw)
In-Reply-To: <20241213215306.54778-1-sj@kernel.org>

DAMON sysfs interface uses damon_callback with its own synchronization
facility to handle commit_schemes_quota_goals command.  But damon_call()
can support the use case without the additional synchronizations.
Convert the code to use damon_call() instead.
