From 88110713ca9dfbb0b6cb8bbb46ef6ecb313d6681 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 20 Feb 2019 12:38:31 +0900 Subject: kbuild: hardcode genksyms path and remove GENKSYMS variable The genksyms source was integrated into the kernel tree in 2003. I do not expect anybody still using the external /sbin/genksyms. Kbuild does not need to provide the ability to override GENKSYMS. Let's remove the GENKSYMS variable, and use the hardcoded path. Since it occurred in the pre-git era, I attached the commit message in case somebody is interested in the historical background. | Author: Kai Germaschewski | Date: Wed Feb 19 04:17:28 2003 -0600 | | kbuild: [PATCH] put genksyms in scripts dir | | This puts genksyms into scripts/genksyms/. | | genksyms used to be maintained externally, though the only possible user | was the kernel build.
