From 1f4910b3affc982a94d665470f0f700225952108 Mon Sep 17 00:00:00 2001 From: Xiaomeng Tong Date: Fri, 29 Apr 2022 14:37:00 -0700 Subject: [PATCH] damon: vaddr-test: tweak code to make the logic clearer Move these two lines into the damon_for_each_region loop, it is always for testing the last region. And also avoid to use a list iterator 'r' outside the loop which is considered harmful[1].
