From a6aaeb841198016083663ae56c568de4e065d090 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 26 Feb 2021 15:25:48 +0900 Subject: kbuild: fix UNUSED_KSYMS_WHITELIST for Clang LTO Commit fbe078d397b4 ("kbuild: lto: add a default list of used symbols") does not work as expected if the .config file has already specified CONFIG_UNUSED_KSYMS_WHITELIST="my/own/white/list" before enabling CONFIG_LTO_CLANG. So, the user-supplied whitelist and LTO-specific white list must be independent of each other. I refactored the shell script so CONFIG_MODVERSIONS and CONFIG_CLANG_LTO handle whitelists in the same way.
