Subject: mm/damon/sysfs: use damon_call() for commit_schemes_quota_goals
Date: Fri, 3 Jan 2025 09:43:55 -0800
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.
