Subject: [RFC PATCH 03/11] Docs/mm/damon/design: document DAMOS_QUOTA_[IN]ACTIVE_MEM_BP
Date: Sat, 28 Jun 2025 09:51:36 -0700 [thread overview]
Message-ID: <20250628165144.55528-4-sj@kernel.org> (raw)
In-Reply-To: <20250628165144.55528-1-sj@kernel.org>
Update design document for newly added DAMOS_QUOTA_[IN]ACTIVE_MEM_BP
metrics. Note that API document is automatically updated by kernel-doc
comment, and the usage document points to the design document which uses
keywords same to that for sysfs inputs. Hence updating only design
document is sufficient.
