+Comment: Specify whether the corresponding process is excluded from LMK victim list.
+         If (yes|1|ok|on), the process is removed from the list.
+         If (no|0|off), the process is not removed from the list.
+         Only app is supported, but service and process are not supported.
+         (system services with System, System::Privileged, and User attrs are
+         already removed from the list in LMK)
