From 214c0eea43b2ea66bcd6467ea57e47ce8874191b Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sun, 10 Nov 2024 10:34:30 +0900 Subject: kbuild: add $(objtree)/ prefix to some in-kernel build artifacts $(objtree) refers to the top of the output directory of kernel builds. This commit adds the explicit $(objtree)/ prefix to build artifacts needed for building external modules. This change has no immediate impact, as the top-level Makefile currently defines: objtree := . This commit prepares for supporting the building of external modules in a different directory.
