Subject: Docs/admin-guide/mm/damon/start: update DAMOS example command
Date: Fri, 16 Jun 2023 19:17:37 +0000
DAMON user-space tool, damo, has deprecated[1] its old DAMOS schemes
specification format. However, an example of DAMON documentation is still
using it. Update the example to use one of the alternative options.
