Subject: [PATCH 3/7] mm/damon/sysfs-schemes: connect damos_quota_goal nid with core layer
Date: Sun, 20 Apr 2025 12:40:26 -0700 [thread overview]
Message-ID: <20250420194030.75838-4-sj@kernel.org> (raw)
In-Reply-To: <20250420194030.75838-1-sj@kernel.org>
DAMON sysfs interface file for DAMOS quota goal's node id argument is
not passed to core layer. Implement the link.
