From f0b0d88a825149ef3b06656886bc211c71dcb852 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Thu, 6 Sep 2018 16:37:24 -0700 Subject: [PATCH] kbuild: modules_install: warn when missing System.map file If there is no System.map file for "make modules_install", scripts/depmod.sh will silently exit with success, having done nothing. Since this is an unexpected situation, change it to report a Warning for the missing file. The behavior is not changed except for the Warning message. The (previous) silent success and new Warning can be reproduced by: $ make mrproper; make defconfig $ make modules; make modules_install and since System.map is produced by "make vmlinux", the steps above omit producing the System.map file.
