From 5934ec1362b235c4341807c28f79b6a596ce1b40 Mon Sep 17 00:00:00 2001 From: Kaixu Xia Date: Thu, 8 Sep 2022 11:13:17 +0800 Subject: mm/damon/vaddr: add a comment for 'default' case in damon_va_apply_scheme() The switch case 'DAMOS_STAT' and switch case 'default' have same return value in damon_va_apply_scheme(), and the 'default' case is for DAMOS actions that not supported by 'vaddr'. It might make sense to add a comment here.
