Subject: [PATCH 02/11] mm/damon/sysfs-schemes: support DAMOS_QUOTA_[IN]ACTIVE_MEM_BP
Date: Tue, 13 Jan 2026 07:27:07 -0800	[thread overview]
Message-ID: <20260113152717.70459-3-sj@kernel.org> (raw)
In-Reply-To: <20260113152717.70459-1-sj@kernel.org>

Add support of DAMOS_QUOTA_[IN]ACTIVE_MEM_BP on DAMON sysfs interface.
Users can use [in]active_mem_bp keyword input to the target_metric sysfs
file to use the new DAMOS quota auto-tune target metrics.
