From 9b2a38d6ef25c1748e3964b0ff30a89e4ed26583 Mon Sep 17 00:00:00 2001 From: Xin Hao Date: Fri, 14 Jan 2022 14:09:53 -0800 Subject: mm/damon: move damon_rand() definition into damon.h damon_rand() is called in three files:damon/core.c, damon/ paddr.c, damon/vaddr.c, i think there is no need to redefine this twice, So move it to damon.h will be a good choice.
