To help them easily understand how DAMON kernel API 848 + can be used, a few sample modules are provided under ``samples/damon/`` of the 849 + linux source tree. Please note that these modules are not developed for being 850 + used on real products, but only for showing how DAMON kernel API can be used in 851 + simple ways.
