From 2e014660b3e4b7bd0e75f845cdcf745c0f632889 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Thu, 28 Oct 2021 14:36:33 -0700 Subject: [PATCH] mm/damon/core-test: fix wrong expectations for 'damon_split_regions_of()' Kunit test cases for 'damon_split_regions_of()' expects the number of regions after calling the function will be same to their request ('nr_sub'). However, the requested number is just an upper-limit, because the function randomly decides the size of each sub-region. This fixes the wrong expectation.
