From 083bc0e1ce91e2a65a1aecdf8d2c5045e5d46c55 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 11 Feb 2020 05:06:34 +0900 Subject: [PATCH] kbuild: fix mismatch between .version and include/generated/compile.h Since commit 56d589361572 ("kbuild: do not create orphan built-in.a or obj-y objects"), scripts/link-vmlinux.sh does nothing when descending into init/. Once the version number becomes out of sync between .version and include/generated/compile.h, it is not self-healing. [How to reproduce] $ echo 100 > .version $ make You will see the number in the .version is always bigger than that in compile.h by one. After this, every time you run 'make', the vmlinux is re-linked even when none of source files is updated.
