From 8d1d3807d501de1467904eb40b0aa345668c3827 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Mon, 29 Jan 2024 17:35:45 -0800 Subject: [PATCH] selftets/damon: prepare for monitor_on file renaming Following change will rename 'monitor_on' DAMON debugfs file to 'monitor_on_DEPRECATED', to make the deprecation unignorable in runtime. Since it could make DAMON selftests fail and disturb future bisects, update DAMON selftests to support the change.
