Subject: Docs/mm/damon/design: categorize DAMOS filter types based on handling layer
Date: Tue, 18 Feb 2025 14:37:08 -0800
On what DAMON layer a DAMOS filter is handled is important to expect in
what order filters will be evaluated. Re-organize the DAMOS filter types
list on the design doc to categorize types based on the handling layer, to
let users more easily understand the handling order.
